Oil-immersed Non-Partial Discharge Transformer for High Voltage Insulation Testing

SUTE Oil-immersed Non-Partial Discharge Transformer is a specially designed high voltage test transformer used for partial discharge measurement and power frequency withstand voltage testing of electrical equipment.

Unlike conventional test transformers, this transformer adopts optimized insulation structure, high-quality transformer oil insulation and advanced shielding technology to minimize internal partial discharge and electromagnetic interference during high voltage testing.

It provides a clean and stable high voltage test source for transformer manufacturers, GIS manufacturers, power equipment companies, research institutes and high voltage laboratories.

The transformer is widely used for insulation performance verification of power transformers, cables, switchgear, bushings, insulators and other high voltage components.

Working Principle

Working Principle of Oil-immersed Non-Partial Discharge Transformer

During high voltage testing, partial discharge generated inside the test equipment itself may affect the accuracy of measurement results.

The Oil-immersed Non-Partial Discharge Transformer is designed to reduce its own discharge level through:

• Optimized electric field distribution
• High insulation strength oil insulation system
• Multi-layer electromagnetic shielding structure
• Low-noise transformer design
• Improved insulation coordination

The transformer provides a stable AC high voltage output with extremely low background discharge, allowing accurate detection of partial discharge signals from the tested equipment.

This makes it especially suitable for sensitive insulation tests where accurate PD measurement is required.
