The DTSY738 series three-phase electronic watt-hour meter is adopted latest micro-electronic technology, used to measure active electric energy of three-phase AC whole rated frequency is 50/60Hz, coordination meter age of positive and negative. This series meters have two mode of cut-over: Cut over directly and cut-over by mutual inductance electronics. The performance is in comformity with the technical requirements for three-phase electronic watt-hour meter stipulated in GB/T17215-2002 Class 1 and 2 Static AC Active Watt-hour Meter standard.
