Description

technical field [0001] The invention relates to the technical field of leakage testing, in particular to leakage current testing equipment. Background technique [0002] Leakage current refers to the current formed by the surrounding medium or insulating surface between electrically insulated metal parts, or between live parts and grounded parts, through its surrounding medium or insulating surface, in the absence of a fault applied voltage, according to According to the UL standard, the leakage current is the current that can be conducted from the accessible parts of household appliances, including the capacitive coupling current. The leakage current includes two parts, one is the conduction current through the insulation resistance, and the other is the displacement current through the distributed capacitance. Leakage current is one of the important signs to measure the insulation of electrical appliances, and it is also the main indicator of product safety performance. ...
