Wiring method of Electrical Current Transformer

- Jan 06, 2021-

The selection of the electrical current transformer wiring method for measurement is related to the grounding method of the neutral point of the power grid. When it is an ineffective grounding system, a two-phase Electrical Current Transformer should be used, and when it is an effective grounding system, a three-phase Electrical Current Transformer should be used Generally, the Electrical Current Transformer, which is an electric energy metering device that charges a fee, should be connected to a component-phase connection (that is, a two-phase four-wire or three-phase six-wire connection method). Transformer can use two-phase three-wire or three-phase wiring.
