Sulphur hexafluoride (SFó) gas insulated switchgear (GIS) is widely used in electrical power supply system and therefore needs regular preventive maintenance. In this research work, a reliable and effective diagnostic technique was used to detect SFó byproducts caused by partial discharge (PD) occuring as a result of more that one defect, named as a hybrid defect. A 0.2-MPa presurrised coaxial chamber...
Gas insulated switchgear assumes an indispensable equipment for high voltage transmission of electrical energy because of its focal points of high unwavering quality and execution, smaller in measurements and extraordinary compatibility with the environment. It utilizes sulphur hexafluoride gas as its insulant and coolant in view of its high dielectric quality and superb circular segment extinguishing...
A reliable diagnostic technique of Gas insulated switchgear condition monitoring is used in this research for the detection of Sulphur hexafluoride gas (SF6) decomposition products due to its high sensitivity and anti-electromagnetic interference; it is known as decomposition by-product method. A simulated coaxial decomposition chamber was designed and used to simulate the decomposition of SF6 under...
