Simulation and Characterization of Micro-Discharge Phenomena Induced by Glitch Micro-Defects on an Insulated Pull Rod Surface

Energies
The reliability of GIS (gas-insulated switchgear) circuit breakers significantly depends on the condition of the insulated pull rods, with micro-defects on their surface posing a potential risk for micro-discharges and breakdown incidents. Experimentally

Characteristics investigation of R407C in high voltage applications as an alternative to SF6

Results in Engineering
The concept of life without electrical power is not possible. All the industrial, domestic zones etc., requires power to operate, which is transmitted by means of overhead high voltage transmission lines from generating stations to sub-stations.
