| Abstract: | The widely used method to verificate combined instrument transformer is to verificate the current transformer and voltage transformer separately and then determine wether the combined instrument transformer is qualified or not.An overall test method that fits for the combined transformer＇s operation state is proposed.And the method of calculating the overall error,the advantage of the overall test and how to choose the standard devices are also discussed. |
