Under the influence of damp and impurity environment on electrical products, electric leakage on insulation may be caused between live parts of different polarity or between live parts and grounding metal, and the generated arc may cause breakdown and short circuit to electrical appliances or electric erosion of materials due to discharge, or even lead to fire disaster. Leakage tracking test is a destructive test conducted on insulating materials to simulate the above conditions, which is used to measure and evaluate the relative leakage tracking resistance of insulators under the action of electric field and water containing impurities under the specified voltage. It is applicable to solid electrical insulation materials and products of electrical and electronic products and household appliances, such as relay sockets, transfer switch covers, contactors, etc.
