World's First 10kV HV Energy Measurement Device Successfully Developed

China has successfully developed the world's first 10 kV/1000 A HV energy measurement device and the new three-phase four-line virtual ground 10 kV HV energy field calibration device, according to the National Institute of Metrology.

These devices can solve the problems of the overall live-work inspection and calibration of energy measurement devices operating at high voltage, which makes China the first country in the world to have a 10 kV HV energy measurement device and a live HV energy field calibration device in its true sense.(Zuo Ya)
