Product Description

20kVA/100kV High Voltage AC Withstand Test System

The 20kVA/100kV High Voltage AC Withstand Test System is intended for insulation verification of electrical apparatus that require an AC high-voltage test before commissioning or service. By applying a controlled 50Hz/60Hz voltage to the test object, it helps identify insulation weaknesses and provides a basis for electrical quality assessment.

The equipment adopts an Oil Filled Test Transformer and a Manual Voltage Control Console. The transformer is responsible for stepping up the input voltage to the required 100kV level, while the control console provides direct adjustment of the applied test voltage. The configuration is particularly appropriate for users looking for a reliable, traditional high-voltage testing arrangement with uncomplicated operation.

Product Parameters

Product Advantages

Application Scenarios

1. Power transformer external insulation testing
2. Distribution equipment inspection
3. Medium-voltage switchgear testing
4. CT / PT insulation withstand testing
5. Porcelain and composite insulation testing
6. Bushing and surge arrester testing
7. Electrical laboratory verification
8. Power equipment maintenance testing

Test Object Recommendation: Before selecting the system, the customer's test voltage, required capacity, load capacitance, leakage current, and test duration should be considered. High-capacitance loads such as long cables may require a resonant AC test solution instead.
