Abnormal Analysis of Potential Transformer Based on MATLAB

HUANG Wen;LU Guoxiao;TANG Chenxu;HU Zhiwei;State Grid Deyang Electric Power Supply Company;Huaxin Conslting Co.,Ltd.;  
Aiming at the abnormal of PT voltage when10 kV ground faultoccurred in the 110 kV substation,the common types of the secondary wiring error of potential transformer were analyzed.The common error and failure features of the PT secondary wiring error were summarized and a way of thinking for similar fault analysis was provided.The MATLAB/Simulink was used to build a simulation model to analyze the fault,and the correctness of the analysis was verified.
