1.3 Busbar system
The following busbar systems can be installed: busbars (see fig. 3 and 4), distribution bars (see fig. 5, 6 and 7), protective and neutral conductor bars (PE+N/PEN) (see fig. 4). 1.3.1 Busbars : The busbars are arranged in the rear section (busbar compartment) of the cubicle horizontally in two selectable levels: Double busbar systems are located at the upper and lower level. Single busbar systems are located at the upper or Iower level, as required. The cross-section of the busbars in both levels can be different. For double busbar systems separate, parallel or coupled operation is possible. Depending on the current 2, 4 or 8 (2 x 4) conductors per phase are used. Cubicles for front and rear operation have a common busbar system. The busbar system can be realised both as 3-pole or 4-pole version. The busbars are divided into sections corresponding to the sizes of the switchgear shipping units. Units having busbars of different cross-sections can be coupled together (required short circuit withstand to be considered).
1.3.2 Distribution bars They provide the connection link between the busbars and the modules. ln the fixed, plug-in, disconnectable and railable module design they are arranged vertically in the busbar compartment (see fig. 5). As an alternative the use of a multi-function separator (see fig. 6) or a metal separation wall (see fig. 7) is possible for plug-in, disconnectable- and railable modules. If using the metal separation wall (see fig. 7) the openings for contacting are covered by protective covers (degree of protection IP 20). ln the withdrawable module design they are embedded into the multi-function separator made of insulating material (degree of protection lP 20) and held in place and arc prooved covered by distribution bar covers. As an alternative they could be covered by a metal separation wall with protective covers (degree of protection IP 20). The grid for contacting is in this solution 4E. The distribution bars can be installed in one length over the total cubicle height, however, sectionalizing is possible, e.g. for coupling for plug-in, disconnectable, railable and withdrawable technique. As a maximum, two 4-poIe distribution bar systems can be installed for plug-in, disconnectable, railable and withdrawable technique. If using the metal separation wall only one 4-pole distribution bar system can be installed.

1.3.3 Protective and neutral bar The protective bar (PE) is mounted horizontally in the lower front section of the cubicle and is directly connected to the frame. Parallel to this the neutral bar (N) is mounted on insulators. The lengths of the bars correspond to the switchgear shipping unit lengths. The protective connection bar is arranged vertically in the cable compartment. Parallel to this the neutral connection bar is mounted on insulators. PE N PEN All PE+N/PEN-bars and connection bars are punched according to a grid system which permits the bars to be mounted in the cubicle and the outgoing cables to be connected as required.
1.4 Modular add-on parts

1.4.3 630A . SR .
1.4.3 Plug-in, disconnectable and railable technique Plug-in, disconnectable and railable modules (up to 630 A) are connected to the distribution bars by means of plug-in contacts.
The LV HRC load break switch type SR constitutes a type of plug-in module. The complete unit is mounted directly on the frame and connected through its own contact elements to the distribution bars. 1.4.3.1 Plug-in modules
1.4.3.1 25mm 9 1800mm 600mm
The plug-in module technology basically consists of supporting plates made of sheet steel with an alu-zinc coating. See fig. 9. Modules of any size may be built in a 25mm grid up to a height of 1800 mm (standard) which comprise one or several supporting plates. The equipment compartment width of standard modules is 600 mm. The modules are fastened directly to the MNS frame using tapping screws secured with a screw cage. If necessary, supporting plates are provided with cut-outs for contact units which serve for contact with the distribution bars. When installed without a multi-function separator, the empty slots will be covered. On the outgoing side of the modules, the connections are made via terminals or directly to the switchgear units.
Depending on their design, modules are operated from inside or from outside if a rotary handle has been fitted.

2.4 Unloading and transport at site
The truck can be unloaded by crane or fork-lift truck. The loads must be lowered onto a flat surface. 2.4.1 Ground transport By fork-lift truck (see fig. 24). By lifting and conveying devices. In an emergency, with rollers (min. 3 pieces). For roller transport the wooden cross-beams must be removed (only for cubicles with transverse sections up to 1200 kg) (see fig. 26). Switchgear cubicles have to be transported only in the vertical position. Tilting and canting must be avoided (see fig. 24). Single cubicles (cubicles without withdrawable modules, circuit breaker cubicles without circuit breakers) may be briefly tilted into the horizontal position if the height of the doorway to the place of erection does not permit vertical transport. ln this case the cubicle sections must be supported over a wide area. Cubicles may easily tip over when transported with a hand-pulled truck. Therefore the distance between the wooden cross beam or the pallet and the underground should not be more than 3 mm (see fig. 24).

3.4 Erection
3.4.1 Erection and connection of the cubicles The erection of the cubicles should be carried out, as described in the following: 1. The shipping units which are to be erected in one row have to be aligned accurately and checked that they are vertical. Doors and panels must not be twisted or stressed. The erection can start at the left or at the right. 2. The frames of the shipping units have to be screwed together (see fig. 31). The vertical sections for front operated units are already fitted on the left front and rear with 4 special nuts. For front and rear operated cubicles, the vertical sections at front left and rear right are fitted with the special nuts. 3. The side walls for the end cubicles have to be fastened. For this purpose, taptite or torx screws M6x10 (see fig. 33) have to be used. During fastening the side walls it has to be made sure that at least at one bolted connection a protective conductor connection is realised by placing a contact washer underneath. 4. Additionally to the vertical sections or if the access to the screw joints in the vertical sections is obstructed by installed equipment, the bottom sections can be screwed together using the frame connectors which are encIosed (see fig. 32). For the initial tightening of the thread-forming screws an eIectric or compressed-air operated screw-driver should be used. For tightening torques for bolted frame connections refer to chapter 5.14.

5. The busbars as well as the protective and neutral conductor bars have to be bolted at the transport divisions using the connections provided (see fig. 34/35). Only ESLOK-sealed screws together with one conical spring washer each are to be used. The connecting points for the busbars are accessible through partition wall between the cable and busbar compartments. This partition wall must be closed after the bars have been secured. Elongated holes at the ends of the bars ensure adequate adjustment within the tolerances set. lf the erection is properly carried out the holes will match up as required. Drilling is not permissible, due to the resulting chips. Contact surfaces do not need a special pretreatment. In case of dirt, the contact surfaces should be cleaned with a soft cloth. Do not use a metal brush or chemical liquids. In case of double busbar systems, the bars should be deburred or slightly phased (on both sides +0 +1 45° -15 with 1 -0,5 mm). Refer to chapter 5.14 for tightening torques for bolted connections of busbars, protective and neutral conductor bars. 6. The protective conductor (PE or PEN) is to be connected to the PE/PEN bar. Additional connections to the central earthing system can be made at any point of the perforated PE/PEN bar. Local regulations must be complied with. 7.

3.5 Fastening methods to foundation
The erection of switchgears having the cable entries at the bottom requires a foundation with an opening or a cable duct. The cubicles should preferably be erected on a base frame which is either embedded in the concrete fIoor or rests as false floor on supports. ABB ±1 mm /1m (. DIN ISO1101 2 / 1000 ) When erecting the base frame the following must be observed: The base frame should be aligned and checked under the supervision of an ABB fitter. The horizontal tolerance of the frame must not exceed ±1 mm over a length of 1 m. This is to be ensured by using suitable levelling devices (e.g. spirit level, 1 m long surveyors rod). The frame must not ondulate ( according to DIN lSO 1101) 2 / 1000
Die Nivellierung der Fundamentrahmen kann z. B. mit einstellbaren PRESTOJACK-Nivellierspindeln (siehe Abb. 39) erfolgen. 39 20mm ( ( ) M8 40).
The leveIling of base frames can be performed e.g. with PRESTOJACK levelling spindles (see fig. 39). During erection the switchgear is welded or screwed to the base frame (see fig. 39). The length of the weld seams at the front and rear of each cubicle should not be less than 20 mm. All weldings must be protected against corrosion by a coat of paint (e.g. zinc paint). ( The screwed connection is carried out through the transverse section. The mounting hoIes required for metal straddling dowels M 8 must be drilled during erection (see fig. 40). ). When false floors are used, notice that: Tolerances are the same as for the base frame.
. ). 20 kN/m
20mm ( ).
The subsoil must be firm, so that the tolerances are not exceeded by settling of the soil (especially when using insulation layers and adhesives). The false floor has to have a carrying capacity of p=20 kN/m (Compression load from top to bottom). 500 mm During erection the switchgear is welded or screwed to the false floor. The length of the weld seams at the front and rear of each cubicle should not be less than 20 mm. Then a reliable earth connection is provided. All weldings must be protected against corrosion by a coat of paint (e.g. zinc paint). lf welding is not possible, the switchgear can be bolted to the false floor. The necessary mounting holes should be driIled on site. Care should be taken to ensure that the base sections of each cubicle rests evenly on the supports. Taking into account the bending radius of the cables and adequate accessibility, a minimum floor height of 500 mm is recommended.

4.6 Withdrawable units size 4E up to 48E
Withdrawable units size 4E up to 48E are built-up of sheet steel components which constitute the supporting frame for the electrical components and the contact elements. The hinged front cover offers the advantage of easy accessibility to the built in components from the front side. Opening the front cover with a key is only possible in isolated, test or OFF-position of the withdrawable unit. If a parallel coupling is installed, opening of one lock is sufficient. Opening of the front cover while the operating handle is in ?ON“-position is only possible with a screw driver (see chapter 5, fig. 75).
OFF ON 75)
If opening the front cover while the operating handle is in ?ON“-position it is possible to touch live parts.
The withdrawable unit can be equipped with an instrument panel made of insulating material for the installation of measuring, operating and indicating instruments. The hinged instrument panel is mounted to the withdrawable unit and sticks out through a cutout in the front cover. This panel remains in position when the front cover is opened. If the front cover is open, the instrument panel can be tilted down by unlocking the locking lever on the left and right side of the panel. After tilting down the instrument panel a better access to the equipment both in the withdrawable unit and the instrument panel is provided. The main switch is operated by the operating handle which is also used for the mechanical and the electrical interlocking. A micro switch with maximum 2 NO and 2 NC contacts is provided for the electrical interlocking.

“MOVE“
Moving of the withdrawable module The withdrawable unit can only be moved, if the operating handle is in position ?MOVE“. This ensures that it is not possible to move a withdrawable module under load. “MOVE“ For moving a withdrawable unit the operating handle has to be brought to the position ?MOVE“ and the withdrawable module has to be pulled out with the use of the two handles. When the unit starts moving the operating handle immediatly moves back to the position ?OFF“ and the withdrawable unit interlocks after 30 mm in the isolated position. In this position the main and control contacts are disconnected. For further moving of the withdrawable unit the operating handle has to be switched to the position ?MOVE“ again. Afterwards the withdrawable module has to be pulled out further. Before removing the withdrawable unit from the cubicle completely the
“OFF“
withdrawable unit interlocks again to avoid being pulled out from the cubicle uncontrolled. To release this safety stop it is necessary to press down the lever on the left side of the withdrawable unit (see fig. 85). If the withdrawable unit which should be moved is installed in a high position in the cubicle the safety stop can be released by supporting the withdrawable unit with the right hand from below and releasing the lever with the left hand. Afterwards the withdrawable unit can be removed completely from the cubicle. Depending on their size withdrawable units have a high weight. Therefore the following safety measures have to be obeyed by all means:
4E 12E
After moving out the withdrawable unit halfway from the withdrawable module compartment the operator has to grasp the withdrawable unit from below under the sides (for withdrawable units size 4E and 8E). 12E For withdrawable units size 12E and bigger the withdrawable unit should only be withdrawn by two persons. For this the operators should be located at one side of the withdrawable unit each and grasp the withdrawable unit from bellow (12E) or at the provided hand grips located at the side walls (> 12E). The withdrawable unit should not be left longer than necessary in the position of the safety stop, because the centre of gravity is already outside the cubicle in this position. Disregarding of this regulation can lead to mechanical damage at the withdrawable unit.
>12E
Withdrawable units in isolated position or in the position of the safety stop are not to be used as help for climbing because persons can be endangered and/or the switchgear can be damaged.
“TEST“
The test position can be achieved without moving the withdrawable unit by turning the operating handle to the position ?TEST“. The operating handle can be locked in the positions ?OFF“ and ?TEST“ by using up to three padlocks. Removing of the unit can be prevented by an additional mechanical lock (protection against theft) which additionally can be installed in the front cover.
“OFF“ For withdrawable units that are not being used the operating handle must be in the position ?OFF“.
4.7 Besondere Hinweise
4.7 Special information
When the installation is in operation ensure that the doors and the front covers of the withdrawable modules are closed, the withdrawabIe modules are interlocked, the ventilation louvers are not abstructed or clogged
Maintenance work, such as replacing fuses etc., must only be carried out by suitable instructed personnel observing the safety rules. . When working on switchgear cubicles the following regulations must be observed: The national and international safety rules (e.g. VDE 0105, regulations for the operation of power installations). The specific maintenance instructions of the installed devices. When making modifications to cubicles it may be necessary to interrupt the operation of adjacent parts of the installation, depending on the extent of the work and the type of design. For modifications inside the cubicles it is necessary to reconsider the changed heat balance. The allowed limit of temperature-rise inside the switchpanel must not be exceeded. In case of doubt please contact your appropriate ABB branch. The use of ESLOK-secured screws renders maintenance of the bar connections unnecessary. After fault situations the checks are to be carried out just as before commissioning.

5.3 Withdrawable technique
The following description refers to the standard modules. For modules differing from the standard version separate descriptions should be applied for. The multi-function separator is arranged between the busbar and the equipment compartment. lt covers the complete height and width of the equipment compartment and fullfils the following functions: Holding of distribution bars. . Fastening and covering of distribution bars by means of the distribution bar cover. Protection against formation and propagation of arc faults. As an alternative for the multi-function separator the metal separation wall can be arranged between the busbar and the equipment compartment. It covers the complete height and width of the equipment compartment and is used for covering the distribution bars. The contact openings of the distribution bar covers fulfill IP 20 and therefore conversion is made possible without the need of interruption of operation for the cubicle (see fig. 86).

5.5 Examination of MNS contact systems within the scope of plant revisions
According to the applicable national and international standards and provisions (e.g. DlN 57 105 part 1/ VDE 0105 part 1; BGV A2), electrical plants must be maintained in an orderly condition by their operator. For all works in connection with the activities required for this purpose, all relevant determinations of the MNS manufacturing instructions and MNS product information sheets must be observed and complied with in addition to the valid safety regulations and all relevant provisions. The former include the following:
BGV A2 MNS
. / SR
?Installation of power contacts" ?Greasing of power contacts“ ?Tightening torques of bolted connections" which you will find in this chapter, too. Each module (withdrawable / plug-in module, fused SR elements, or withdrawable module condapter) is subject to the following mandatory visual inspections prior to installation in the cubicle (before first installation in the workshop as well as after each revision). The visual inspection of the contact system should include the following items resp. their observation is strongly recommended: 8E/4 8E/2 Damages (e.g. worn silver resp. tin layer, signs of inadmissible heating, etc.) at the contacting surfaces of the MNS contacts and their counterparts (distribution bars, withdrawable module condapter, outgoing cable connection unit). Contacts movable and properly snaped into position in the withdrawable module rear wall or contact apparatus housing. Deformation of contacts (bent), mechanical damages. Medium-force fit of the contact spring (withdrawable modules 8E/4 and 8E/2) in its specified position. lnsulation behind crimping swollen. Contacts greased.
In cases of doubt, the contact force may be measured using a special testing device. In the event of doubts additionally measure the contact clearance with a slide gauge or standard gauge. The specified values of 4.7 +0,05 -0,2 mm must not be exceeded or left short.
+0,05 -0,2
8E/2 8E/4 ABB
Please note: The size of the contact opening need not be checked for the contact 4E (e.g. using a gauge block), because this check does not make sense due to construction.
lf irregularities are detected, we recommend replacing contacts, complete withdrawable module rear wall for 8E/2 and 8E/4 modules or the entire contacting system and/or informing the respective ABB Service department in order to determine and coordinate further measures.
Before checking the distribution bars or the withdrawable module condapters disconnect the cubicle from the power supply!

5.6 Greasing of contact areas
5.6.1 Greasing of power contacts Greasing the contacts is a mandatory prerequisite for reaching the operating cycles to which the unit is certified through type test as the grease reduces the wear of the contact area finish. Furthermore, the force needed for withdrawing the modules is reduced. Contact areas of the power contacts are to be cleaned and greased whenever the following conditions apply: the assembly works and testing routines have been completed in the workshop after a revision or after 100 plug-in cycles or after 2 years, whichever is earlier immediately before installing the module in the cubicle. Grease to be applied: Contact grease Klüberlectric KR44-102 Use a brush to apply the grease. Avoid excess grease on the contacts. If modules are supplied as loose parts, they should be greased at the building site. For contact areas to be greased, see figures 89 and 90

Contacts of the withdrawable module condapter as well as of SR switch disconnectors are to be treated similarily.
Withdrawable modules which are to be supplied separately, the contacts should only be greased on site. The following quantities of 7 g (8 ml) tubes are to be supplied together with the modules for this purpose: For 1 up to 4 modules of size 8E/4 and 8E/2 1 tube each For module sizes 4E up to 48E 8 contacts each For plug-in modules up to 400 A, 4 contacts each over 400 A, 4 contacts each

5.6.2 Greasing the fuse links The contact lugs of the LV HRC fuses must also be greased every time before being inserted into the fuse holder of any type of switching device (OS / OESA, SLP/ XLP, SR elements, etc.). If the fuses are supplied loosely, 0.5 tubes of contact grease are required for each module (1 set = maximally 4 fuses for all sizes).

5.7 Lubrication of withdrawable module interlocks
When the withdrawable modules have been in use for some time, it may be necessary to lubricate the interlocks of the withdrawable modules size 8E/2 and 8E/4 (dependent on the environmental conditions and the tightness). For this purpose the mobile parts must be sprayed with a lubricant (approx. 1 sec.). Thereafter a functional test must be carried out. Lubricant to be used: Molycote Omnigliss Spray, Liquid high-pressure lubricant in 300 ml tins Manufacturer: Dow Corning GmbH D-65201 Wiesbaden/Germany 4E 48E Lubrication of withdrawable module interlocks for module sizes 4E up to 48E is not necessary during maintenance works.

5.8.1 Installation Once inserted in the withdrawable module rear wall 1TGB120050P0001, or the contact housings 1TGB120048P0001 and 1TSA233000P0007, the contact must be properly engaged. Successful engagement is indicated by a single, audible click, and can be verified by pulling the cable. Please note! The new contact type does not click a second time once it has passed the engagement hook like the old contact type.
In case the contact does not properly engage, it has to be checked whether the engagement hook has the proper shape (and does not, e.g., have any extrusion edges), or whether the engagement hook is broken. Parts whose engagement hook is not properly shaped, or broken, have to be replaced.

5.8.2 Testing The withdrawable module assembly must be tested as follows prior to installation in the cubicle (first installation and after revisions): MNS ). Visual inspection (The contacts must not have any visible damages). Contact opening size (refer to: Examination of MNS withdrawable module design contact systems within the scope of plant revisions). Snapping in (It must not be possible to press the contacts back manually). Contact float (The contacts must not sit firmly in the chamber, they must be mobile in all directions in order to ensure a tolerance adjustment).
5.8.3 Contact plating Contact plating with silver or tin Application of different platings -> -> Silver (Ag) Tin (Sn) -> Standard -> Option on customer request
Identification The type of plating is visually not distinguishable. That is why contacts are marked: ” on the contact fingers: impression of “Ag” or “Sn” Combination of differently plated parts in one switchgear It applies in principle for the withdrawable and railable technique: Es ist nicht zul?ssig, Schienen und Kontaktsysteme mit unterschiedlicher Oberfl?chenvergütung miteinander zu kombinieren! It is not permitted to combine busbars and contact systems with different coatings!
: 30 SR RPC 8E/4 :
Exceptions: The mix of contact material for the following systems, where the contacts are not moved more than 30 times. SR- Switch disconnectors Plug-in modules (not railable modules) RPC modules Module condapters 8E/4 and 8E/2 (only the connection between distribution bar and condapter) tin-plated busbars and contacts at the incoming side of a system and silver-plated busbars and contacts at the outgoing side.
MNS For clear verification also all parts of the MNS busbar system are marked with “Ag” or “Sn”.
5.9 Paintwork damage
5.9.1 Preparation of the damaged Iocation Surfaces or locations soiled by grease/oil shall be cleaned with an aliphatic cleaning agent using a linen cloth.
5.9.2 Execution The paintwork repair set whose colour matches that of the plant to which it is attached (if ordered) shall be used for paintwork repairs.

5.15 Commissioning and maintenance of MNS reactive power compensation systems
5.15.1 Commissioning and maintenance In the worst case, compensation systems are permanently operated with their maximum power. Therefore, good ventilation is to be ensured in the place of installation in order to prevent the ambient temperature from exceeding the max. admissible limit of 35°C (mean value over 24 hours). Malfunctions or an insufficient compensation power can be best determined (although too late) by checking the reactive power demand (electricity bill). If the following points are noted during commissioning and the regular maintenance works, a loss in compensation power can be detected at an early stage.
1. 2. a) b) 4 c) d) e) IP 32 .
1. Check ventilation in the place of installation. 2. Check the construction: a) Above and below each individual module (or the modules), an air supply and air discharge must be available. b) If the cubicle bottom plate is closed (no air supply through bottom plate), there must be at least 4 ventilation slots. c) No compartment bottom plates or other installations may be present in the cubicle which might adversely affect ventilation. d) For protection class > IP 32 or installations which deviate from c) above, forced ventilation (or a reduced amount of equipment) is required. e) A transverse partitioning must be installed between the cable compartment and the equipment compartment. 3. Check the settings and the functioning of the controller (switching outputs). 4. Check contactors for sparking when switching and for faultless making and breaking operations. The maintenance intervals of the contacts of the capacitor contactors depending on their number of ? switching operations (can be read off ESTAmat RPR) are subject to the manufacturer?s instructions.
Do not operate capacitor-contactors by hand!
5. 5. The current consumption of the system and the modules serves as an indication for a loss in capacitance if a capacitance test (which requires safety disconnection of the compensation system) is not possible; in this case, the currents and voltages in each phase must be measured simultaneously. (However, current measurement is only a rough criterion in view of possible current distortions caused by harmonic waves!) 6. a) b) c) d) e) 7. 7. : 1 . . . 6. Before touching the capacitors: a) Wait for at least one minute until the capacitor is discharged. b) Protect the system against reclosing. c) Verify safe isolation from supply. d) Short-circuit the capacitor terminals among each other and with the housing in order to compensate for differences in potential. e) Protect neighbouring live parts against accidental contact. Perform a visual inspection of the electrical equipment. (Leaks such as oil leakages, bulging of the capacitor lid or housing,
condition of terminals, switches, protective devices, reactors, discharge resistors, conductors.) 8. 9. 10. 11. 9. Clean the modules as well as the air supply and air discharge regions of each cubicle (ventilation louvers, filter mats).
Check protective devices and switches for faultless operation.
10. Check bolted connections and clamping units. 11. Measure capacitances and log measured values. (The capacitances of the compensation capacitors may change due to inadmissible heat rise, expiry of the useful life, overvoltages, etc. Experience has shown that the inductance values are not subject to major changes.) Please note: Before measuring capacities discharge resistors must be disconnected from capacitors. Setpopint values are given on the module nameplates.
5.15.2 Correction of faults In the event of malfunctions during commissioning, the cubicle wiring (especially in the area of the transport partition) should be checked first. Other possible faults include the following: Controller display remains dark: Check control voltage. Controller does not switch in additional steps (although request is available): Measuring voltage or current not or improperly connected. Check fuses. Wrong transformer ratio. Lowest step power is too high. C/K / Inappropriate C/k value setting / value too low. Controller switches very often: Switching time (too) short with quick load changes. Step power too low. Wrong C/k value setting. C/K cos . setpoint is not reached: Lowest step power is too low. Inductive current too low. All steps are permanently active: Undercompensation, i.e. installed leading reactive power is not sufficient. Check control voltage. Check LV HRC fuses of the modules. 5A 1A 5 A transformer connected to 1 A controller measuring input.
Too many steps active (overcompensation): Check transformer installation. Check controller settings.
Wrong measuring voltage connection (phase-phase and phaseN exchanged). cos display does not coincide with additional power factor meter reading: wrong voltage measuring connection (phase-phase and phase-N exchanged). slight deviations may be due to inaccurate measuring units and/or different measuring points.

5.16 Measuring of the insulation resistance
Insulation measurement is of fundamental importance to an electrical system. Furthermore, it is the only type of measurement that serves for preventive fire protection. The insulation resistance is a complex resistance in the form of a parallel connection of an ohmic resistor R W and a capacitance C. The equivalent resistance is a variable quantity that is influenced by various parameters. This is illustrated by the following equivalent circuit diagram:
RW : RD: RU: Ri : Rt
constant equivalent resistance dielectric resistance voltage-dependent resistance current-dependent resistance time-dependent resistance
For which protective measures do you have to measure the insulation resistance? The insulation resistance must be measured for all protective measures! This refers to protective measures without protective conductor and with protective conductor. Insulation measurement is required according to DIN VDE 0100, but also to other standards, such as IEC 60439-1, Section 8.3.4, EN 60204, DIN VDE 0105, VDE 0110.

5.16.1 DIN VDE 0100 610 5.3
5.16.1 Which insulation measurements have to be peformed? DIN VDE 0100 part 610 specifies insulation measurement between the conductors in Section 5.3: If the circuits contain electronic components, such as semiconductors, these sensitive components must by no means be damaged by the high measuring voltages.

If the insulation resistance is too low in this case, the consuming equipment must be isolated, and the system and consumer must be measured separately. Prior to commissioning, the following circuits must be measured: All line sections between any 2 overcurrent protection devices. The section following the last overcurrent protection device without any connected consumer equipment.
5.16.2 Which minimum insulation resistance must be available? In order to exclude the influence of the capacitive reactance, the measurements must be performed with DC voltage. For the values of the measuring voltage and the minimum insulation resistance, please refer to the table below. DC [V] Measuring-circuit voltageDC [V] 250 [M ] Minimum insulation voltage value [M ] 0,25
Protective measure and rated voltage / Safety extra-low voltage, functional extra-low voltage with safe isolation / Protective separation 500 V, / Rated voltage 500 V, and functional extra-low voltage without safe isolation > 500 V, 1000 V / Rated voltage > 500 V, 1000 V
5.16.3 30%. DIN VDE 0413
5.16.3 Required measuring accuracy The operating error within the marked measuring range must not exceed 30 % with respect to the value reading. This error range permitted by DIN VDE 0413 part 1 initially seems to be very high. From the equivalent circuit diagram above, however, it becomes obvious that the insulation resistance is composed of a fixed component and four other components which may vary according to different parameters. This results in the large variation range. 5.16.4 Minimum readings (Note recommended operating error of - 30 %!)

Protective measure or rated voltage Extra-low voltage Rated voltage Rated voltage Remark: 500 V 500V, 1000V
Reading [M ] 0.36 0.7 1.4
The assessment of the measured values has to take into account the overall condition of the system!
5.16.5 Capacitive charges For longer leads and cables, first allow the capacitive charging process to be completed and the indicator of the measuring device to come to a standstill before performing the reading.
If a capacitive charging process was observed, the leads must be discharged after measurement in order to prevent electric shock.

5.18 Maintenance intervals
5.18.1 General 5.18.1.1 Legal conditions Electrical switchgear and controlgear systems require permanent preventive maintenance not only for technical and economic reasons. In an effort to define the due order in the energy sector, the government dictated a number of legal provisions from which the requirements of preventive maintenance can be derived.
5.18.1.2 Preventive maintenance At the moment, no technical standard provides comprehensive guidance on the preventive maintenance of electrical distribution networks and equipment. The principles require, i.a., that the electrical systems and equipment must be operated in accordance with the rules of electrotechnology, which includes preventive maintenance. All defects must be immediately remedied. In the event of imminent danger, electrical systems must no longer be operated.
DIN 57105
/VDE 0105
Even the provisions of DIN 57105 part 1/VDE 0105 part 1 do not contain any specific requirements beyond general information on the preventive maintenance of electrical systems. The most important information on preventive maintenance is summarized in item 5, "Preservation of proper condition and repetitive testing". This item stipulates, i.a., that high-current systems must be kept in proper conditions in accordance with the standards governing their installation. Defects of electrical systems must always be remedied immediately, i.e. without any culpable delay. If danger to persons, property or the environment is imminent, defective electrical systems or equipment must be immediately put out of operation. They must not be used in defective condition. A switchgear system is defective if safety is jeopardized by its operation. DIN In order to be able to timely recognize any defects that might have occurred after commissioning of the electrical systems or after a repair or modification thereof, DIN 57105 part 1 / VDE 0105 part 1 demands the performance of repetitive tests, however, without detailing concrete terms for the test cycles. Repetitive tests serve for the evaluation of the proper condition of electrical systems and equipment. Repetitive tests include: a visual inspection trial runs measurements other tests

5.18.2 Maintenance of MNS switchgear systems 5.18.2.1 General safety instructions
: BGV A2, §6 5 :
For cleaning the switchgear system inside, the system or component must be off circuit. It is not recommended to use compressed air for purging dusty systems.
Safety at work: The procedure for performing switching operations is prescribed by the implementing instructions on BGV A2, §6: The off-circuit condition must be established prior to commencement of the work and must be ensured at the place of work for the duration of the work in compliance with the following five safety rules which must be applied as a standard:
5 : �C �C �C �C �C
Five safety rules Prior to commencement of work: �C Safety isolation �C Protection against re-closing �C Verify off-circuit condition �C Earthing and short-circuiting �C Cover or barrier adjacent live parts
These five safety rules must be observed as safety measures for work at electrical systems and equipment. 5.18.2.2 : MNS . 5.18.2.2 Health and safety Please note the following information: In accordance with the valid regulations all installation and maintenance work involving MNS-switchgear systems may only be performed by qualified personnel. For manipulations at low-voltage switchgear system components, the component to be manipulated must be isolated!!! The power supply to the capacitor by a remote auxiliary power source, if any, must also be isolated. When the system has been isolated, allow the voltage stored in the capacitor to be discharged by the discharging resistors by waiting for one minute. As an additional safety measure, the outgoing capacitor circuits must be tested for discharged condition using an insulated cable. Check whether the current transformers have been short-circuited before they are isolated or connected. The automatic capacitor must be installed in accordance with the standards IEC 60831-1&2 and all national regulations. A short-circuit may pose dangers to human life and destroy equipment! Therefore, it is of vital importance to use suitable tools and instruments for commissioning or inspection of electrical systems.

5.18.3 Maintenance and inspection of MNS switchgear systems 5.18.3.1 General Especially in the case of systems associated with a higher risk (e.g. nuclear power plants) the operation and maintenance must be handled extremely carefully in order not to exceed the acceptable limit risk. For information on the mechanical and electrical life of electrical equipment, please refer to the relevant product documentation. All maintenance work and the required tightening torques relating to the electrical equipment in use must also be carried out in accordance with the binding manufacturer?s instructions.
