Product Description

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

The 5kVA/50kV Power Frequency PD-Free AC Withstand Test System is a professional AC high-voltage testing solution for maintenance organizations working with electrical power infrastructure. It can provide the required test voltage for insulation withstand verification before equipment is returned to operation, helping testing personnel identify insulation problems through controlled AC voltage application.

The system combines a Motorized Operation Console, Power Supply, PD-Free Test Transformer, and Voltage Divider. The motorized console allows operators to regulate the test voltage electrically, while the PD-free transformer supplies the high-voltage AC source. The voltage divider provides voltage feedback for the testing circuit. This configuration can be adapted to factory, laboratory, maintenance, and commissioning environments.
