Description

technical field [0001] The invention belongs to the field of measurement technology, in particular to the technology of high voltage and high current test. Background technique [0002] General electrical products must pass the quality inspection before they go on the market, so that users can feel at ease when using electrical products, and can relatively reduce the occurrence of accidents. When conducting quality inspections on electrical products, most of them use withstand voltage machines and grounding impedance measuring equipment to measure electrical products, and then judge the internal resistance of their electrical products, and judge whether they have reached the withstand voltage that meets safety regulations. and withstand current conditions. [0003] The EU regulation IEC-60050-826 stipulates that when the output voltage is higher than 1000 volts, the leakage current of the high voltage side to the ground must be less than 3mA (milliampere), which makes quite...
