依据标准:GB/T6553-2003
Under the influence of moisture and impurities in electrical products, insulation leakage may occur between charged parts of different polarities or between charged parts and grounded metal. The resulting arc can cause breakdown, short circuit, or material erosion due to discharge, and even lead to fire. The leakage tracing test is a destructive test conducted on insulation materials to simulate the above situation, used to measure and evaluate the relative resistance of insulators to leakage tracing under the action of an electric field and impurity containing water at a specified voltage. It is suitable for solid electrical insulation materials and their products in electrical and electronic products, household appliances, such as relay sockets, conversion switch covers, contactors, etc.
