Abstract
The utility model discloses a high voltage electric energy meter gauging device which comprises a low voltage current signal generating device whose output end is connected with a voltage booster and a current booster. The output ends of the voltage booster and the current booster are connected with a high voltage heavy current loop. The high voltage heavy current loop on which the gauged meter is working samples the high voltage heavy current signal to a standard electric energy meter at the lower voltage end using a high voltage current mutual inductor and a high voltage mutual inductor. The energy impulse outputted by the gauged meter is transmitted to a comparison gauging display device at the lower voltage end to compare with the high frequency gauging impulse of the standard electric power meter and compute the electric energy computation error. The high voltage electric energy meter gauging device achieves the integral measuring precision gauging of the high voltage measuring device which greatly improves the working efficiency.
