HIGHEST / LOWEST INDICATING INSTRUMENT - RL Series
EXTERNAL WITH ALARM CONTACT - ERL Series
RL Series
Recently, power plant and factory etc. have been promoting automation
and unmanned rationalization of receiving electric power distribution
equipment. At the time of control power, can use this model meter to makesure the maximum (minimum) value for the instantaneous or the certain time.
This instrument meter has more suitable for record the occurrence ofground accident and the short circuit accident like Vo Meter, because thisindicating instrument had added with the record pointer can indicate themaximum (minimum) value of instantaneously.
In addition, this series meter be fully satisfied with high reliability and alsowith standard JIS C 1102-1~9 (IEC 60051-1 matching)
RL－80C

Features► 2 size: 110mm degree and 80mm degree.
► AC voltage, ammeter and transformer indicator is all in one type, without
accessory box.
► Mechanical strength is strong.
► Record pointer can be reset by push the button at the cover.
Electromagnetic reset combined use type also can be manufactured.
► Meter with Incombustible material can be manufactured as specify.
► Adopting transducer with electronics technology, more type product is
expanded.

ERL Series
Power plant and factory etc. have been promoting automation andunmanned rationalization of receiving electric power distribution equipment.
RL－110C

For power management, this instrument meter can make sure the maximum
value for the instantaneous or the certain time.
This instrument meter had added with contact less type warning upper
limit, so the alarm signal will be operate in the time when electric variable
exceeds setting value. With the application of the output contact, please use
in rationalization such as automation or laborsaving in measurement control
and meintatenance of electric equipment.

Features► With maximum alarm contact output(Contact capacity: AC250V, 0.5A resistance load)► AC voltage, ammeter and transformer indicator is all in one type, without
accessory box.
► Record pointer can be reset by push the button at the cover.
ERL－110CH

Electromagnetic reset combined use type also can be manufactured.
► Meter with Incombustible material can be manufactured as specify.
► Adopting transducer with electronics technology, more type product is

Highest / Lowest Indicating Instrument - RL Series
Application Vo Meter
With 3 phase circuit, AC voltmeter can measure the abnormal electric potential when the earth faults the grounding.
Or as for generated voltage at the time of earth fault, it can grasp the maximum value by record pointer.

Usage
As shown in the figure 1 at below, connected 3 unit primary side single phase VT type like Y and it can carry out theneutral point to ground. Delta connection of the secondary side and open 1 place to connects Vo Meter at there.
When 1 full line ground accident is occurs, 3 times voltage will impress to Vo Meter between line voltage like figure at
below.

Selected Maximum Scale
Selects the value which fraction does not occur at 1.5 times at phase voltage or primary line voltage of VT is generally
max. scale value of Vo Meter. For commonness meter line phase, intrinsic maximum scale value become same,
whichever select the max. scale value of line voltage or phase voltage.
Please have a reference at below Ex. max. scale value figure as our company standard phase voltage scale display.
There is a single phase type VT and three phase all in one type VT for Vo Meter VT use. Primary rating of 3 phase all
in one type VT is line phase, but when wire connect like Y inside primary and the neutral point is taken, it becomes thesame relation as the single phase type VT of primary rating /√3.
Please look at the following table for the example rate of VT, max. scale value and intrinsic max. scale value of meter.
