GIS AC Withstand Voltage Test System Variable Frequency Series Resonant Test Equipment for High Voltage GIS and Substation Electrical Equipment

The GIS AC Withstand Voltage Test System is specially designed for high-voltage GIS and large-capacity substation electrical equipment.

GIS systems have significant capacitance and require appropriate AC high-voltage testing equipment during manufacturing, installation and commissioning.

A variable frequency series resonant system provides a practical solution by adjusting the frequency to achieve resonance between the reactor and GIS capacitance.

• GIS AC withstand voltage test
• GIS insulation test
• AC dielectric strength test
• Substation equipment withstand test
• Busbar AC test
• High-voltage equipment commissioning test
• Automatic frequency sweep
• Automatic resonance tuning
• Test voltage measurement
• Test current monitoring
• Protection monitoring

GIS and other large-capacitance electrical systems may require significant reactive power during AC testing.

The series resonance principle can help reduce the required input power and equipment size for suitable applications.

Q: Can the system be customized for different GIS voltage levels?
A: Yes. The output voltage and capacity can be designed according to the GIS specifications.

Q: Is GIS AC withstand testing different from cable testing?
A: Yes. The test object capacitance and voltage requirements are different, so the resonant system configuration must be selected accordingly.
