SF6 gasplant Repair for extra high Voltages

Circuit ConfigurationProtective MeasuresArrangement and ModulesHigh voltage substationsare points in the power system where power can be pooled from generating sources, distributed and transformed, and delivered to the load points. Substations are interconnected with each other, so that the power system becomes a meshed network. This increases the reliability of the power supply system by providing alternate paths for flow of power to take care of any contingency, so t…See more on electrical-engineering-portalEquipments of power transmission - SlideShare• SF6 is an electro-negative gas. • It has strong tendency to absorb electrons. • When contact are opened in a high pressure flow of SF6 gas, arc produced. • Free electron in the arc are captured by the gas which build up enough insulation strength to extinguish arc. • It is much effective for high power and high voltages
