Relay Testing Laboratory

Relay Testing Laboratory

The relay testing lab of PSTI is equipped with English electric make distance relay panel and the overcurrent relay panel along with associated testing kits. These relay panels are installed about 15 years ago. They are in perfect working condition for testing the directional distance relays and the overcurrent relays.

The lab is also equipped with M/s ABB make non-switched static protective relays panel with distance, differential, fuse failure, over-current and restricted earth fault relays. The above relays can be tested with the associated testing kit.

There is a disturbance recorder cum fault locator in the laboratory supplied by M/s C&D Instruments (India) Ltd. This instrument in association with the distance relays available in the laboratory can be used to demonstrate various types of faults, distance to fault etc.

The Relay Testing Laboratory is equipped with the following equipment:
