Title: Improvements in and relating to electrical measuring instruments
IPC: G01R25/00
Filed: 1933-05-17
Abstract: 401,696. Power-factor measurements. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Rowell, R. M. ; 23, West Colony Road, Lynn, Massachusetts, U.S.A.) May 17, 1933, No. 14296. Convention date, May 18, 1932. [Class 37.] An apparatus for measuring or indicating power-factors on polyphase circuits, particularly applicable to circuits with unbalanced loads, comprises a pair of relatively movable members composed of elements each comprising a current coil and two crossed potential coils responsive to voltages in quadrature with each other, the current coils being mechanically connected together to form one of the relatively movable members, while the potential coils are mechanically connected together to form the other of said members. In the arrangement shown in Fig. 1, for a three-phase circuit having three conductors 1, 2, 3, the current coils 11, 13 are fixed in position and excited from the conductors 1, 3, while the two sets of crossed potential coils A, Band C, D are mounted on a common shaft 15 which carries a pointer 16 cooperating with a scale 17. The power component coils A, C are connected in series with resistances RA, Rc between the conductors 1 and 3, respectively, and the conductor 2. The quadrature potentials are obtained by connecting resistances, Ro, RB and RD to form an artificial neutral point N, Fig. 2, the coils B, D being connected between this point and the conductors 1, 3. In a modified arrangement, Fig. 4, autotransformers 24, 25 are connected between the conductors 1 and 3 and the conductor 2, and the coils A-D are connected, as shown, to points in the autotransformer windings calculated to give the required voltages in quadrature. In the arrangement shown in Figs. 1 and 2, six hair springs or flexible connections 18-23 are required to make the connections between the movable coils A-D and the external portion of the apparatus, but the number of flexible connections required may be reduced to four by connecting the coils with resistances Ro, RB, RD and R13 in a combined star-delta arrangement as shown in Fig. 5, each of the coils in this arrangement being directly connected to two other coils. For a two-phase circuit with three conductors, the potential coils may be connected directly in the phases. For a polyphase circuit having a neutral conductor, a power-factor instrument having as many mechanically connected units as there are phases is used. An arrangement for a threephase circuit with line conductors 1, 2, 3 and neutral N is shown in Fig. 8. In this arrangement, the current coils 37, 38, 39 are connected in the three line conductors, the power component potential coils 43, 44 and 45 are connected between the line conductors and the neutral, while the quadrature potential coils 46, 47 and 48 are connected across the line conductors as shown.

Abstract: 714,538. Air-blast switches. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. June 6, 1952 [June 7, 1951], No. 14296/52. Class 38(5) In an air-blast switch having a rod-like contact 5 fixed at its lower end in a tubular insulator 4 and a movable contact 14 fixed to an operating piston 15 in a cylinder 16 mounted on the insulator, the single tubular insulator 4 serves as a blast passage and insulates the contacts from each other and from earth. The lower end of the contact 5 may be formed as a fixing plate which is secured to the inner wall of the insulator by bolts 6. A 'bracket 7 on which the arm 8 of a disconnecting switch is pivoted, may also be secured to the insulator by the bolts 6. To open the switch, a coil 22 is energized to open a pilot valve 12 so that compressed air in a container 1 is able to force down a piston 26 to open the blast valve 27. The air blast moves the piston 15 against the bias of a spring 17 to open the contacts 5, 14, the arc drawn being extinguished by the air blast through the contact 14. After the valve 27. has been opened, compressed air flowing through a passage 24 acts on a piston 23 to open the disconnecting switch 8, 9. On the closing of the valve 27, the contacts 5, 14 automatically reclose and a valve 25 may then be actuated to admit compressed air above the piston 23 to reclose the isolating switch 8, 9.
