Product Description
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.

Why Use Resonance for GIS Testing?
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.
FAQ
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.
