Test the electrical performance of relays and protection with AC voltage (including phase voltage, line voltage, zero sequence voltage, positive sequence voltage, negative sequence voltage), AC current (including phase current, line current,) amplitude, phase, frequency, impedance and other variables.

The step size can be manually controlled, and the step size can be changed by any setting variable

Changes in output can be controlled

Monitor changes in the input volume

Action time can be tested

Multiple continuous state tests

Provides a variety of state sequence settings

Provide a variety of time control, input control, manual trigger for state switching

Can set various types of faults, including single grounding, two-grounding, interphase short circuit, three-phase short circuit. Fault type Instantaneous fault, permanent fault, transformational fault, and can control the fault transition time

Can provide constant current, constant impedance and other test methods

It can simulate the opening and closing time of the short-circuit device
