SF6 Gas Insulated Equipment | Vaisala electric power industry uses SF6 to insulate switchgears, circuit breakers and other equipment used in electricity transmission and distribution. To ensure the integrity of SF6 gas as an insulator, the amount of water vapor in SF6 gas should be kept to a minimum.
Research status of replacement gases for SF6 in power ...· This paper reviewed the research status of SF 6 replacement gases in order to help researchers study the new substitute gases. This paper is organized as follows: Sec. II introduces the properties of SF 6, which is the important reason that it can be used widely in the power industry, and points out the disadvantages, which is the reason for looking for substitute gases.Cited by: 2
Current transformer testing - Megger need for a comprehensive current transformer testing regime is evident when the alternative is considered: a catastrophically damaging current transformer fault. A fault leading to an open secondary could cause the primary current to overwhelm the insulation, causing the winding to short circuit.
