1、 The function of arc resistance tester

Overvoltage and overcurrent triple protection polymer material arc resistance testing machineAs a specialized instrument for detecting the arc resistance performance of electrical equipment, it has become one of the important tools for safety performance testing of electrical equipment. Mainly by simulating the arc phenomenon that electrical equipment may encounter during actual operation, the arc resistance performance of insulation materials for electrical equipment is tested. During the testing process, the instrument will apply a certain voltage to the tested sample to generate an arc. By observing the generation and development process of the arc, as well as the damage to the sample after testing, the arc resistance performance of electrical equipment can be evaluated.
