Advanced AC Resonant Test System for Transformer, Cable and GIS Insulation Withstand Voltage Testing | High Voltage Hipot Testing Equipment

The AC Resonant Test System is specially developed for high voltage insulation testing applications where large capacitive loads require stable AC voltage output.

Compared with conventional power frequency test transformers, the resonant test system provides efficient high voltage generation through resonance technology, reducing the required power supply capacity and improving testing efficiency.

It is an ideal solution for:

• Transformer manufacturers
• Power transmission companies
• Substation testing teams
• Electrical engineering contractors

Used for:

• AC withstand voltage test
• Insulation strength verification
• Preventive maintenance testing

Applicable for:

• XLPE cable acceptance test
• Cable commissioning test
• Cable insulation diagnosis

Supports:

• GIS
• CT/PT
• Circuit breakers
• Insulators

The system automatically searches resonance points and adjusts output frequency to achieve stable testing conditions.

Integrated protection functions:

• Over voltage protection
• Over current protection
• Flashover protection
• Emergency shutdown
• Zero voltage start protection

Q: Is this equipment suitable for outdoor field testing?

A:
Yes. The modular structure allows convenient transportation and installation for outdoor high voltage testing.

Q: Does it support different international standards?

A:
The system can be designed according to customer testing standards and project requirements.
