Xin Shen, Hongchun Shu, Min Cao · Sensors and Materials · 2019
According to the issue of transmission characteristics of a capacitor voltage transformer (CVT), which leads to the inaccuracy of power grid voltage harmonics values, a new test system and a method of measuring the capacitive current of a CVT were proposed.A comparison of the results of the conventional test method and actual power grid harmonics verified the validity and accuracy of the proposed test method, and a test of the voltage harmonics in the actual power grid showed that the test system can completely satisfy the requirements of testing the voltage harmonics.
