Low Partial Discharge High-Voltage AC Test System for Power Utilities' Substation Insulation Verification and Electrical Equipment Maintenance

Product Description

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

The 5kVA/50kV Power Frequency PD-Free AC Withstand Test System provides power utilities with a dedicated source for AC insulation withstand verification. It can be incorporated into inspection and maintenance procedures where electrical equipment needs to be tested before commissioning, after repair, or during periodic condition checks.

Its four-part configuration consists of a Motorized Operation Console, Power Supply Unit, PD-Free Test Transformer, and Voltage Divider. The console provides electrically controlled voltage adjustment, while the PD-free transformer produces the AC high-voltage output. The voltage divider supplies the measurement function required for monitoring the test voltage.
