Relay test kit

Listing ID #3709334

The Relay Testing Equipment is a portable apparatus which is designed for checking the operating characteristic of protective relays on site. Ever present in every day operation of electrical power system is the possibility of the occurance of faults . Since a relay in the system is called into action to deal with a fault only once in a long while, its failure to operate correctly on that occasion means Severe damage to plant or waste of money spent on installation. Periodic Field testing is the best way of ensuring the integrity of the protective relays. But the position is complicated because of the fact that the protective relay is solely concerned with fault conditions and hence it cannot readily be tested under normal operating conditions.
