电压互感器标准装置

电压互感器标准装置是采用同步标定点进行比较测差来确定被检电压互感器相对标准电压互感器的误差。标准电压互感器比被检电压互感器高两级。此种方法简单直观，对测量装置的准确度及电源的稳定度要求不高，且满足检定规程。The voltage transformer standard device uses synchronous calibration points for comparative difference measurement to determine the error of the voltage transformer under test relative to the standard voltage transformer. The standard voltage transformer has two accuracy classes higher than the voltage transformer under test. This method is simple and straightforward, imposes low requirements on the accuracy of the measurement apparatus and the stability of the power supply, and complies with the verification regulations.
