The application of relay protection tester
The relay protection tester is an important test equipment in the power system. It is mainly used for testing all kinds of traditional relays and protective devices. Meanwhile, it is also used for testing modern microcomputer protection. It is particularly worth mentioning, that plays an important role in testing transformer differential protection and spare automatic cutting devices. Specifically, the relay protection tester can test every single component in secondary scheduling, these components include current, voltage, time, difference, balance, negative sequence, distance, power direction, inverse time lag, frequency, synchronous, re-closing, and other relays. In addition, it can also simulate a variety of simple or complex transient, permanent, transition failures for the test of a whole group of drives.
When the transmission system lines in operation occur such as wind, snow and ice, lightning strikes, or external damage, the relay protection tester can quickly select the targeted trip fault analysis Line breaker (switch). The relay protection tester can quickly select the targeted trip fault analysis line breaker (switch), which ensures the stability and safety of the power system operation.
