The difference between the applied voltage and the leakage current test is mainly due to the different voltage applied to the product under test. Withstand voltage test applied voltage is much higher than the rated voltage, medical equipment, 2 layers of MOPP test voltage up to 4KV, the test is between the fire zero line and electrical shell, mainly to detect the electrical insulation properties. Leakage current is applied 1.06 times the rated voltage, testing the fire zero line and ground line between the leakage current products. Both are important items in the quality testing of electrical appliances, are to protect the safety of consumers, the national standard mandatory test click to learn more
The purpose of the test is different from the purpose of the voltage withstand test and leakage current test is different. Voltage withstand test is to check whether the product can withstand a certain intensity of overvoltage, non-normal working conditions, the tested product voltage withstand test qualified, indicating that its ability to withstand voltage fluctuations in the use of the process is strong, not easy to produce their own damage and other issues. Leakage current is to test the product in normal operating conditions, the insulation part of the current through the human body is lower than the safety current, the product leakage current test qualified, indicating that its normal use will not produce electrical damage to the human body and other issues.
