Assessment of Gas Insulated Switchgear measurement tools

Assessment of Gas Insulated Switchgear measurement tools

Nov 06, 2020For older switchgear, a condition assessment should be performed to establish that the equipment remains in a suitable condition for further service. Partial discharge testing and infrared scanning can be used to obtain data on the performance of the insulation system and the integrity of the switchgear busbars and cable terminations. The frequency of such tests will depend on the duty, age and condition of the switchgear.
