Three-phase Electronic Watt-hour Meter

Description of Three-phase Electronic Watt-hour Meter:
The three phase electrical type watt-hour meter is a kind of whole electrical meter which measures active energy or reactive energy electric energy consumption in frequency 50Hz or 60Hz three phase AC electricity net. The series meter is a new product developed by our company according to market demand and adopts advanced special low power loss solid state, concentrative technique and SMT technology. This watt-hour meter can indicate user accumulative total electric energy consumption by mechanical register or LCD displayer.

Features of Three-phase Electronic Watt-hour Meter:
1. It delivers high accuracy, strong reliability, wide load, low power loss, level error curve, saving energy and materials etc.
2. The technical performance of active energy three phase watt-hour meter completely conforms to National Standard GB/T 17215-2002 and International Standard IEC6 2053.
3. The technical performance of reactive energy three phase watt-hour meter completely conforms to National Standard GB/T17882-1999 and International Standard IEC1268.
