Product Brief Introduction

Three-phase Electronic Watt-hour Meter is adopted latest microelectronic technology, Used

to measure active electric energy of three-phase A.C whose rated frequency is

50/60Hz,Coordination meter age of positive and negative. This series Meter have two mode

of cut-over: cut-over directly and cut-over by mutual inductance electronics. The

performance is in conformity with the technical requirements for three-phase Electronic

Watt-hour Meter stipulated in GB/T 17125-2002 Standard.

Function and Feature

1. Measure three-phase active electric energy, Do not need calibrate for long-term

operation
2. Three phase power supply, Loss one(any one wire of three-wire) or two(any tow wire of

four-wire)phase, uninfected measurement
3. Wide service temperature range
4. Assuming function of defect phase indication or voltage indication
