Methods for Hi-pot of Lamps and Lanterns usually include Hi-pot test and leakage current test. Here's a quick rundown of the test methodology: 1. Withstand voltage test The withstand voltage test is used to test whether the Lighting Fixture can withstand a certain high voltage under the rated voltage to verify its insulation performance. During the test, connect the Lighting Product to the test equipment, apply a certain high voltage, generally 1.5 times the rated voltage of the lamp, and continue for a period of time to observe whether there are any abnormal conditions such as leakage, arc, and spark. 2. Leakage current test The leakage current test is used to detect the presence of electrical phenomena in lamps to verify their safety performance. During the test, the lamp is connected to the test equipment, a certain high voltage is applied, generally 1.2 times of the rated voltage of the lamp, and the leakage current of the lamp is measured to determine whether it exceeds the specified safety limit. When conducting high-voltage testing, it is necessary to pay attention to the selection and operation specifications of test equipment to ensure the accuracy and reliability of test results.
