750kV AC Resonant Test System and Machine for Substation Equipment Cable and Transformer Dielectric Testing

6000kVA 750kV AC Resonant Test System

The 6000kVA 750kV AC Resonant Test System is specially developed for high voltage AC withstand testing of large-scale electrical equipment. By applying advanced resonant technology, the system can generate high voltage output with reduced power demand, providing an efficient testing solution for equipment with large capacitance such as transformers, GIS, and high voltage cables.

Designed for power utilities, transformer manufacturers, testing laboratories, and engineering companies, the system supports both factory testing and on-site commissioning applications. It is an ideal choice for high voltage insulation assessment and preventive maintenance of modern power systems.

The system is widely used for transformer testing, including power transformers, reactors, and other high voltage components. It helps manufacturers perform insulation verification and ensure products meet required electrical performance standards before delivery.

For GIS equipment and high voltage cables, the AC Resonant Test System provides stable AC voltage output for withstand tests. It is suitable for substation commissioning, cable acceptance testing, and periodic maintenance inspections.

In power plants and electrical engineering projects, the equipment can be deployed as a portable high voltage testing solution. Its flexible design allows engineers to conduct reliable insulation tests in different working environments.
