| Abstract: | The principle and method for judging 48 wiring modes of the three-phase and three-wire Watt-hour meter by using pincers power factor meter are discussed in this paper. The result shows the right-wiring, error-wiring and wiring mode of Watt-hour meter can be judged by following steps: measures the power factor of the circuit, the input current direction and the phase angle of the voltage and current in the two measurement units, then does some simple calculation and compares with other power expressions from the different wiring measurement. |
