The development progress of high voltage Watt-hour meter

High voltag Watt-hour meter is a new energy measuring product in distribution network, which has got over the shortcomings of the existed high vohag energy measuring equipments. This paper puts forwards the design scheme of high voltag Watt-hour meter, in which signals are sampled by electronic transformer, and the method of high voltag singlephase direct energy measurement is adopted. The advantages of high voltag Watt-hour meter are compared to the traditional high vohag energy measuring equipment. At last, the paper presents the result of the examinations about high voltag Watt-hour meter, such as essential error, insulated ability, partial discharge, etc.
