The HZJB-660T is a six-phase relay protection tester engineered to test a wide range of relays — including current, voltage, inverse time, power direction, impedance, differential, low frequency, synchronization, frequency, DC, intermediate, and time relays — as well as microcomputer protection devices. It can simulate various complex transient, permanent, and transitional faults for comprehensive testing.
