Analysis of Electrical High Voltage Test for Primary Equipment in Substation
Taking the insulation resistance and absorption ratio testing of the main transformer winding in a 110kV substation as an example,this paper explores the application effect of electrical test optimization strategies.The experiment was optimized for quality control and safety control,and based on this,the handover test data before the main transformer was put into operation,the preventive test data after one year of operation,and the test data after applying optimization strategies were compared.The results show that after applying the optimization strategy,the insulation resistance and absorption ratio are closer to the handover test data,indicating that implementing the optimization strategy can improve the accuracy and reliability of electrical high voltage test results,and provide a basis for the maintenance work of primary equipment in substations.
