Abstract UHV DC Converter Station DC Field have a lot of Multi-Column Parallel, the lightning arrester must when handing over the test or preventive test for DC reference voltage and leakage current test, and now for the lightning arrester reference voltage and leakage current test method or the conventional AC arrester test methods, the conventional method is only suitable for single lightning arrester or more than series arrester, more than for the parallel operation of surge arrester without corresponding test method. In this paper, a low pressure microamps table test, the test method can be without dismantling equipment, accurately measure the test data, reduce the workload, and to a certain extent, to avoid damage caused by the demolition of surge arrester.
