Analysis and Application of Partial Discharge Testing Technology for Transformers
Partial discharge test is a main method to judge whether there is any defect in transformer insulation.In this paper,the principle of partial discharge is introduced,and the preparation work,system calibration,and test procedure of partial dis-charge testing are analyzed in detail.The partial discharge testing system platform for transformers is designed and built,the test-ing and comparative analysis of partial discharge are conducted,which can meet the requirements of partial discharge testing for transformers.It has guiding significance for transformers partial discharge test.
