Product Description

5kVA/50kV Partial Discharge-Free AC Test System

The 5kVA/50kV Partial Discharge-Free AC Test System provides a specialized high-voltage testing platform for users who need to examine insulation performance under power-frequency AC voltage with reduced background discharge. It is particularly suitable for transformer manufacturers and electrical laboratories conducting insulation quality evaluation and high-voltage acceptance tests.

The system consists of a Motorized Operation Console, Power Supply, PD-Free Test Transformer, and Capacitive Voltage Divider. The control console manages the voltage application process, while the dedicated test transformer produces the required AC high voltage with low partial discharge characteristics. A capacitive voltage divider is incorporated for high-voltage measurement, allowing the complete test circuit to be operated as an integrated system.
