Multi-Application System
A properly designed reactor combination can support multiple types of test objects.

High Voltage Capability
Different system configurations can be designed for medium-voltage, high-voltage and extra-high-voltage testing.

Modular Structure
Reactors can be connected in series or parallel according to voltage and current requirements.

Q: Can the same resonant system test both GIS and cables?
A: In some cases, yes. However, the reactor configuration must match the voltage and capacitance requirements of each test object.

Q: Can GIS testing be performed on site?
A: Yes. Variable frequency resonant systems are widely used for GIS AC withstand voltage testing and commissioning applications.
