The device is intended for in-place control of technical condition of all types of foreign and Russian switches (air, oil, gas-insulated, vacuum) on all classes of tension from 6 kV to 1150 kV.
It is further development of the universal PKV/U2 device as a result of which it was increased:
- number of discrete channels for control of provision of contacts with the 12th to 20;
- number of channels for connection of resistive sensors from the 2nd to 12;
- switchboard current with 10A to 35A of constant or alternating current;
- number of channels of sensors of movements with 1 to 3.
The device is issued in two modifications differing in number of channels of control of resistive sensors, number of channels of sensors of movement and number of sensors of movement: PKV/U3.0 (with twelve channels of control of resistive sensors, three channels of sensors of movement and two or two and more sensors of movement) and PKV/U3.1 (with two channels of control of resistive sensors, one channel of sensors of movement and two sensors of movement). The first device allows to control all types of air switches, including VO-750, VO-1150, VNV-1150, and the second - everything, except three listed.
