Product Description

5kVA/50kV Power Frequency PD-Free AC Withstand Test System

The 5kVA/50kV Power Frequency PD-Free AC Withstand Test System is intended for electrical testing work in power generation facilities. It supplies a controlled AC high voltage for checking the dielectric withstand capability of compatible transformers, generator-related equipment, and other electrical apparatus during factory inspection, maintenance, or commissioning.

A complete system includes a Motorized Operation Console, Power Supply Unit, PD-Free Test Transformer, and Voltage Divider. The console manages the voltage application process, while the dedicated test transformer produces the 50kV AC output under a low-discharge design. The voltage divider is used to obtain the corresponding high-voltage measurement signal, allowing operators to monitor the test voltage throughout the procedure.
