CHJ Series Spark Tester

Power frequency spark machine is actually an online weakness detection instrument. It periodically loads the set voltage value to the insulated wire according to a certain rule, and the conductor part is grounded. In this way, a voltage difference is formed between the conductor and the insulation surface, so that it can be detected whether the insulation layer is defective.
