What's the test method of Automatic Electrical Safety System?
Pls. note that the DC high voltage output is a negative voltage, and the ground is a positive. When testing capacitance, there is a charging process when voltage is applied to both ends of the capacitor. At this time, there is a charging current in the test circuit. When the current is greater than the set leakage current value, the withstand voltage tester will alarm to interrupt the test , it cannot be proceed. Therefore, when the safety tester is testing, the voltage should be increased slowly, and the charging current should be less than the set leakage current value until the test voltage is specified, and the test should be performed. It is not possible to use a fixed voltage, reset-start method for testing. In the AC circuit, it is equivalent to the resistance in the DC circuit. […more…]
