Abstract
There are two off-line test methods for the leakage current of MOAs in HVDC systems, namely the demolition connection method and the non-demolition connection method. The former has an advantage to detect accurately the MOA's reference voltages of U1mA and 75%U1mA while the latter can do the detection very fast and directly. But there is a question, "if the results of the two methods are equivalent", that facing operation departments and testers. With the two methods this paper does a field test on the lightning arrester of convertor in Guizhou-Guangdong +500 kV HVDC transmission system, and analyzes the leak current characteristics of the arrester in various situations, founding that the results with these methods are basically in agreement, and then discusses the feasibility and diversity of the two methods.关键词
