Electrical Breakdown Voltage Tester For Enameled Wire
Introduction of withstand voltage tester:
It is suitable for enameled wire, electronic wire, PVC wire, etc. in air medium, under a certain temperature, the power frequency voltage (48 ~ 62Hz) of high voltage is raised at a specific speed between the insulation layer and the conductor at a specific speed until breakdown, so as to measure the breakdown voltage of the tested object. It is applicable to the method of continuous and uniform voltage rise or step-by-step voltage rise. The AC voltage is applied to the sample until it breaks down. The breakdown voltage value is measured and the breakdown strength of the sample is calculated. The voltage is raised to the specified value by the method of rapid voltage rise, and the sample does not break down for a certain period of time. The specified value is set as the withstand voltage value of the sample.
