Study On The Additional Error Testing Of The Electronic Voltage Transformer

In order to obtain electronic voltage transformer's additional error characteristics, this paper analyzed the impact on the electronic voltage transformer caused by change of temperature, primary connection and harmonic and formulated a reasonable error characteristics test method. Through the error experimental verification of passive and active electronic voltage transformers in the laboratory and comparison and analysis of experimental data, this paper obtained error characteristics about change of temperature, primary connection and harmonic. The conclusion provides an important support for the accurate assessment of the electronic voltage transformer's stability and reliability.
