electrical meter,watt hour meter,watt hour meter. 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 Specification and Technical Data: 1. Rated Current(A)3×1.5(6),3×5(20),3×10(40),3×15(60),3×30(80),3×30(100) 2 Rated Voltage(V)Three-phase four-wire 3×220/380V OR 3×57.7/100V Three-phase Three-wire 3×100V OR 3×380V 3.
