The following figure shows the three-phase watt-hour meter wiring diagram and wiring method:

Picture description: Three-phase watt-hour meter wiring diagram

The three-phase three-wire active watt-hour meter uses a structure in which two sets of driving components act on two aluminum disks (or one aluminum disk) mounted on the same rotating shaft. Its principle is exactly the same as that of a single-phase watt-hour meter.
