Overview

With the smallest volume among the like products worldwide, the WHVM178 energy meter which is specially designed for high voltage metering can be directly involved in the high voltage systems without any CT and PT. It has obtained many technology breakthroughs in the field of high voltage energy metering and innovation patents based on our rich R&D experience. It has been widely applied for outdoor high voltage energy metering. The highlighted features of the meter include high accuracy level, resistance to harsh environment, less weight with smaller volume, anti‐theft, accurate line loss management and harmonic component monitoring, convenient installation, etc. The meter has evolved from the conventional high voltage metering mode of Transformer+Energy Meter to an integrated meter which benefits customers in both high accuracy and portability.
