substation Programmable Three Phase Secondary Current Injection Test Set of Relay

Three Phase Relay Protection Microcomputer Test System, substation Programmable Three Phase Secondary Current Injection Test Set of Relay

Test-330 is a three phase current output and five phase voltage output relay tester with embedded host machine equipped with Complex Programmable Logic Device.

The purpose of secondary injection testing is to check that the protection scheme from the relay input terminals onwards is functioning correctly with the settings specified. This is achieved by applying suitable inputs from a test set to the inputs of the relays and checking if the appropriate alarm/trip signals occur at the relay/control room/CB locations.

The secondary injection test simulates the current and voltage transformer secondaries, by injecting single-phase or three-phase currents and voltages into relays, devices o into the secondary circuits, performing all the corresponding checking and testing with normal and fault conditions. The widest range of equipment for secondary injection test.

Secondary injection test on each relay to prove operation at one or more setting values Primary injection tests on each relay to prove stability for external faults and to determine the effective current setting for internal faults (essential for some types of electromechanical relays)
