Three-Phase Watt-Hour Meter Schematic Diagram

Three-phase watt-hour meter is used to measure the power output (or load consumption) of three-phase ac circuit. Its working principle is exactly the same as that of single-phase watt-hour meter, except that it adopts the way of multiple driving parts and aluminum plates fixed on the rotating shaft in structure to realize the measurement of three-phase electric energy.

 

Three-phase three-circuit active watt-hour meter uses two sets of driving parts to act on two aluminum plates (or one aluminum plate) mounted on the same shaft, and the principle is exactly the same as that of single-phase watt-hour meter.

 

The three-phase watt-hour meter fully meets the technical requirements of single-phase 1 or 2-stage in DL/ T645 -1997 and GB/ T17215-1998.With good reliability, small size, light weight, beautiful appearance, advanced technology, 35mm DIN standard installation and other characteristics;And has a good anti - electromagnetic interference, low self - consumption power saving, high precision, high overload, high stability, anti - electric leakage,Long Service life.
