Wiring method of three-phase watt-hour meter
Feb 01, 2022
In low-voltage three-phase four-wire lines, three-element three-phase watt-hour meters are commonly used.
If the load current on the line does not exceed the range of the watt-hour meter, it can be directly connected to the line.
If the load current exceeds the range of the watt-hour meter, a current transformer must be used to reduce the current.
Three-phase four-wire watt-hour meter, there is a wiring terminal connection diagram on the inside of the wiring slot cover. Refer to wiring. Each terminal has more than one set screw, and wire ends should be sufficiently secured under them when wiring.
