New method that improving temperature stability of electronic voltage transformer in middle voltage

We introduced an electronic voltage transformer which was based on the principle of the voltage divider, and presented the principle and structure of electronic voltage transformer. The impact of the temperature characteristics was also analyzed. Temperature tests of some electronic voltage transformers were carried out at temperatures from -25°C to 40°C. The calculation errors caused by temperature change were analyzed. Results show that selecting the appropriate size of temperature compensation can reduce the errors of electronic voltage transformer caused by the temperature change.
