1. Withstand voltage test, commonly known as “high voltage dielectric test”, referred to as “withstand voltage test”. The basic regulation of selecting the appropriate range of voltage withstand tester is to use the working voltage twice of the object to be tested, and then add one thousand volts as the voltage standard of the test. The test voltage of some products may be higher than 2 × The working voltage is + 1000V. For example, the working voltage range of some products is from 100V to 240V, and the test voltage of such products may be between 1000V and 4000V or higher. Generally speaking, products with “double insulation” design may use test voltage higher than 2 × Working voltage + 1000V standard.
2.The withstand voltage test is more precise in product design and sample making than in formal production, because the product safety has been determined in the design and test stage. Although only a few samples are used to judge the product design, the on-line test during production should be more strict. All products must be able to pass the safety standards, and it can be confirmed that no defective products will flow out of the production line.
3.The output voltage of the withstand voltage tester must be kept in the range of 100% to 120% of the specified voltage. The output frequency of the AC withstand voltage tester must be maintained between 40Hz and 70Hz, and its peak value shall not be lower than 1.3 times of the root mean square (RMS) voltage value, and its peak value shall not be higher than 1.5 times of the root mean square (RMS) voltage value.
4.Different products have different technical specifications. Basically, in the withstand voltage test, a voltage higher than the normal working voltage is applied to the product for testing. The voltage must last for a specified period of time. If the leakage current of a component is kept within the specified range within the specified time, it can be determined that the component is very safe to operate under normal conditions. Excellent design and selection of good insulation materials can protect the user from accidental electric shock
