Portable Relay Tester
-
The protective devices such as relays, overload coils, circuit breakers must be checked regularly to ensure that, they are always ready to operate correctly. If a fault occurs in the equipment, which they are protecting, routine relay testing will quickly detect the faulty, incorrectly adjusted protection circuit and will possibly prevent serious damage to plant or injury to personnel. Apart from checking the protective circuits correctly, it is usually necessary to measure its operating time. The micro controller based time interval meter is used for this purpose in all AJIT brand relay tester.
