Description
Current Injection Relay Protection Tester HME-702 is designed for testing most types of microcomputer protection.
The HME-702 is a professional high accuracy test instrument of protection relays such as differential, earth fault and over current. By output high accuracy current and voltage, the tester simulates fault sampling of transformer secondary and timing the trip command to evaluate the time relays.
HME-702 contains 3 phase current output, range of each phase is 0 to 40Amps; It contains 4 phase voltage output, range of each phase is 0 to 120 V.
For time relay test, it contains 8 channel binary input; for current breaker status simulation, it contains 4 channel binary output.
HME-702 contains DC 110V or 220V auxiliar power supply .
