Variable Frequency High Voltage Test Equipment AC Resonant Voltage Withstand Hipot Test
Product Details
This product is mainly designed and made for AC withstand voltage test, such as the cable of 35kv and 10kv. The separated inductor can satisfy the test requirement of high voltage and low current, and can also meet the demand of low voltage like cable of 10kv, it means it has wide range of application.
This device is consist of variable frequency control Power Supply, Excitation transformer, inductor and capacitance divider.
