Estimated Reading Time: 10 minsPublished: 2005/3/3OverviewIn an electric power system, switchgear is composed of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate electrical equipment. Switchgear is used both to de energize equipment to allow work to be done and to clear faults downstream. This type of equipment is directly linked to the reliability of the electricity supply. The earliest central power stations used simple open knife switches, mounted on insulating panels of marble or asbestos. Power levels and voltages rapidly escalated, making opening manually operated switches too dangerous for anything other than isolation of a de energized circuit. Oil filled switchgear equipment allow arc energy to be contained and safely controlled. By the early 20th century, a switchgear line up would be a metal enclosed structure with electrically operated switching elements, using oil circuit breakers. Today, oil filled equipment has largely been replaced by air blast, vacuum, or SF6 equipment, allowing large currents and power levels to be safely controlled by automatic equipment. High voltage switchgear was invented at the end of the 19th century for operating motors and other electric machines. The technology has been improved over time and can now be used with voltages up to 1,100 kV. Typically, switchgear in substations are located on both the high and low voltage sides of large power transformers. The switchgear on the low voltage side of the transformers may be located in a building, with medium voltage circuit breakers for distribution circuits, along …

Compact, maintenance free and climate independent. For the distribution of electrical energy, Siemens offers various gas insulated switchgear types, which can be used in transformer and distribution systems of power supply companies, but also in industrial medium voltage systems, e.g. mining industry, steel works or paper industry.
70kV sf6 Inspection explain
Inspection for SF6 or vacuum leaks should be performed by train technicians and engineers at ITI who perform services on par with NETA standards. Breaker contact resistance, insulation resistance of each pole to ground, over potential tests, as well as others are all required to be completed at routine intervals for safe operational assurance.

35kV insulating gas weight Disadvantage
Thermal insulators work by trapping bubbles or pockets of gas inside a foam structure. When these cells of gas are filled with moisture, there are significant losses in insulating efficiency. The thermal conductivity of water (at 10 &C) is 0.5 kcal m 1 h 1 &C 1 and that of ice (at 0 &C) is 2 kcal m 1 h 1 &C 1 (about four times the value of water).
