SF6 Air Sensor recovery machines for 400kv

The laboratory is having excellent background noise level of < 2pC at 600kV. This equipment is presently suitable to test partial discharge and C Tan delta of 245 kV equipment. We are also in the process of increasing the rating of the equipment up to 900kV shortly. With this, it shall be capable of testing all 400kV equipment.
