The DTSD156 type electronic three-phase watt-hour meter adopts thelatest microelectronic technology to measure active three phase AC electric energy.with rated frequency 50/60Hz,measuring power of in both forward and reversedirections. This series of digit meter has two modes of cut-over: cut-over directlyand cut-over by mutual inductance electronics. The performance is in conformity withthe technical requirements for three-phase Electronic Watt-hour Meter stipulatedin lEC62053-21-2003 Elctricity metering equipment (ac) static meter for activeenery(class 1 and 2) and lEC62052-11-2003 Electricity metering equipment (AC)Generalrequirements,tests and test conditions part 11.
