SF6 gas insulated series resonant test system is special designed for testing of gas insulation switchgear and gas insulation substations. The system can be connected with the GIS directly, which bring great convenient to the testing.

Compared to oil insulated resonant system, It has the advantages of very low partial discharge level, light weight, small volume and movable.

There are two different design: 30-200Hz variable frequency or 50/60Hz adjustable inductance.
