Abstract

In order to ensure the safe operation of power system, it is necessary to carry out preventive test on MOA regularly. At present, the traditional test method is complex in operation, low in efficiency and high in risk, which cannot meet the development needs of modern power system. Based on the existing test methods, the critical operating voltage and leakage current of metal oxide arrester are tested. A set of test system is designed and the field test is carried out. The maximum error between the test results and the manufacturer's data is less than 5%, which proves the reliability of the system. The test results show that the method and system have the characteristics of simple operation, high security, and can obtain multiple data groups at one time, which can greatly simplify the operation process and improve the test precision. The system has the advantages of simple structure, low cost and good industrial application value, which provides a new direction for the detection of lightning arrester.
