True or False question: Please answer whether it is correct or incorrect. 3 points for a correct answer, 2 points for an incorrect answer, and 5 points for a detailed explanation of the reason. AC withstand voltage tests should also be conducted on secondary circuits of 48V and below.
Error: AC withstanding voltage tests are not required for secondary circuits of 48V and below
Error: The dielectric strength test is the most effective and direct method for assessing the insulation strength of electrical equipment, and it is an important part of preventive testing. Furthermore, since the voltage used in the AC withstand voltage test is generally higher than the operating voltage, the equipment has a substantial safety margin after passing this test; therefore, the AC withstand voltage test is an important method to ensure the safe operation of electrical equipment.
