Arc Extinction Cabinet

Medium voltage Arc Extinction Cabinet

In normal operation, the microcomputer controller continuously detects the voltage signal provided by PT. Once the system has PT disconnection, single-phase metal grounding or single-phase arc grounding, its auxiliary secondary open triangle voltage will immediately change from electrical low level to high level.
