◆ it can accurately simulate the ground faults of different cable positions, and the fault points can be switched between each other
◆ each short circuit circuit has three current-limiting resistors: 1 ohm, 5 ohm, and 10 ohm
◆ it can be controlled by software programming, and the duration of the fault can be set
◆ simulation of ground fault of connected public low-voltage power supply system cable
◆ distribution line fault simulation: including phase-to-phase short-circuit, three-phase short-circuit, single-phase grounding, two-phase grounding, three-phase grounding and other faults
◆ with overheating automatic blocking protection function
◆ including ground fault simulation, low noise, lower inlet, lower outlet, upper exhaust, suitable for indoor work
