Method for transforming secondary loop of voltage transformer of electric energy metering device

The invention discloses a method for transforming a secondary loop of a voltage transformer of an electric energy metering device. In the invention, a transformation scheme is designed according to requirements of DL/T448-2000 'regulation for technical management of electric energy metering device'; and the method for transforming the secondary loop of the voltage transformer of the electric energy metering device is developed aiming at the situations of benefit loss and even economic disputes of a power supply part and a power consumption part because the secondary loops of the voltage transformers of some of the conventional electric energy metering devices cannot meet the requirements of the regulation and accurate metering cannot be achieved.
