| Abstract: | Based on structure,principle and condition-based maintenance requirements of 220 kV capacitor voltage transformer(CVT) ,a new routine test method of CVT without removing the HV lead conductor is put forward.The wiring of routine tests is introduced in detail and the correctness of this method is demonstrated through error analysis of each test,and its effectiveness is verified by Examples.The sampling test among different types CVT shows the new method can be generalized. |
