Arc extinction and harmonic elimination cabinet During regular functioning, the microcomputer controller constantly monitors the voltage signal received from PT. Suppose the system experiences PT disconnection, single-phase metal grounding, or single-phase arc grounding. In that case, the auxiliary secondary open triangle voltage will promptly shift from a low to a high level. The microcomputer controller will then activate. It will determine the type and phase discrepancy based on the alteration in the PT secondary voltage
