SF6-Insulated Reactors have been developed for theuse in Resonant Test Systems with variable frequency for GIS on-site testing and are directly flanged to the GIS. They are also suited to increase the test power of conventional low-power SF6-insulated test transformers essentially by a high voltage-side parallel compensation of the capacitive reactive power. Furthermore they can be equippedwith a SF6-to-air bushing for testing air-insulated components or GIS via air bushings.The design of these resonant reactors is similar tothat of instrument transformers with a combined SF6-oil-insulation and a disk bushing. A capacitive divider for the voltage measurement is integrated in thepressure vessel.

Designed for the measurement of partial discharges (PD) .Available as simple stand-alone measuring instruments but also as computer-aided highly sophisticated measuring and evaluation systems wit PD fault recognition and identification.
