Product Description

20kVA/50kV Power Frequency AC Withstand Test System

The 20kVA/50kV Power Frequency AC Withstand Test System is developed for routine insulation verification of electrical equipment under power-frequency AC voltage. With a 50kV AC output and 20kVA rated capacity, the system provides a practical testing solution for manufacturers and laboratories performing dielectric withstand tests on medium-voltage electrical products.

The system is configured with an Operation Console and an Oil Immersed Test Transformer. The transformer generates the required high-voltage AC output through reliable oil insulation and heat dissipation, while the control unit enables operators to regulate and monitor the testing process. It is suitable for production inspection, quality control, and maintenance testing of electrical equipment.
