Summary of Literature on Failure Analysis of Capacitor Voltage Transformer

摘要


Taking the capacitive voltage transformer (CVT for short) as the research background, the working principle of the capacitive voltage transformer is introduced in detail, and the circuit of the transformer is equivalent and analyzed. In view of the common failures of capacitive voltage transformers, the test methods and numerical changes of each failure are analyzed.
