5kVA 50kV Power Frequency PD-Free Test System with Motorized Console and Voltage Divider Testing Equipment for Transformer Switchgear CT PT GIS Cable Insulation Testing

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

The 5kVA/50kV Power Frequency PD-Free Test System is designed for high-voltage testing applications where a low partial discharge background is required. It provides a controlled AC test environment for evaluating the insulation performance of transformers and other electrical equipment while minimizing unwanted discharge interference during measurement.

The complete system integrates a Motorized Operation Console, Power Supply Unit, PD-Free Test Transformer, and Capacitive Voltage Divider. The motorized console provides controlled voltage adjustment, the power supply delivers stable operating power, and the PD-free test transformer generates the required high-voltage AC output. The voltage divider provides accurate measurement of the applied high voltage, forming an integrated solution for power-frequency insulation testing.

• Low PD Background — The test transformer is designed to provide a low-discharge testing environment for insulation evaluation.
• Integrated System Configuration — Combines control, power supply, high-voltage generation, and voltage measurement in one system.
• Motorized Voltage Regulation — Enables convenient adjustment of the applied AC test voltage.
• Dedicated PD-Free Transformer — Helps reduce unwanted discharge interference during high-voltage testing.
• Accurate Voltage Measurement — The capacitive voltage divider provides a measurement interface for the high-voltage output.
• Complete Testing Solution — Reduces the need to separately configure the major components of the test circuit.

• Transformer partial discharge testing
• Transformer insulation evaluation
• High-voltage electrical equipment inspection
• Laboratory insulation testing
• Electrical component quality control
• Power equipment R&D testing
