Check The Wiring Of The Line Fittings For Any Changes Or Misconnections

Pre-insulated Sleeve Check whether the wiring has been changed or wrongly connected:
Changed wiring means that the original metering circuit wiring has been changed, while wrong wiring means that the metering circuit wiring does not meet the normal metering requirements. During the inspection, for low-voltage customers who have not passed through the transformer, the simple wiring of the energy meter can be intuitively judged based on experience, and for the metering circuit connected through the transformer, it can be checked against the wiring diagram and determined by instrument measurement.
