With the development of the electric industry, capacities of various electric equipments are becoming larger. Accordingly, the quality inspection test system is required to have more test capacity and higher test voltage. If traditional transformers are used in this system, transformers and voltage regulators must be very large in size due to the high requirement of test capacity. However, heavy and large test equipments would be inconvenient for onsite test, CHX-L，I series large current variable inductance series resonant test equipment can overcome disadvantages of traditional equipments, thus being an ideal choice of onsite AC voltage withstand test.
