  • Leak Testing High Voltage Switchgear - LACO Technologies

    May 14, 2015 · In this article we will cover production leak testing of gas insulated high voltage switchgear and associated subassemblies. Gas-insulated high voltage switchgear typically use a sulfur hexafluoride (SF6) gas to minimize arcing when the circuit breaker is activated. Leak testing of the subassemblies and finished product provide confidence that the sufficient pressurized SF6 gas will be contained inside the unit to prolong its functional life.

  • Measuring Dew Point and Moisture in SF6 Gas

    Sulfur hexafluoride (SF6) gas is an inert insulating gas of high dielectric strength and thermal stability, often used in the power sector for insulating high voltage lines, circuit breakers, transformers and other switchgear equipments. As sf6 is an inert gas, it can’t cause corrosion but in the presence of moisture it will cause formation of highly corrosive acidic by-products, such as Hydrogen Fluoride (HF) and Sulfur dioxide (SO2).

    Maintenance RequirementsPreparation Before MaintenanceMaintenance ProcedureSwitchgear SparesLubrication of Operating MechanismsTroubleshooting GuideMaintenance covers a wide range of activities, all of which are required to keep the switchgear in ready condition at all times to enable it perform its functions satisfactorily. The parts subjected to normal wear and agingneed to be serviced for ensuring full reliability of the operations. These parts may be mechanical components or electrical components. The interval at which the maintenance should be carried out depends upon the following factors: 1. The number of short-circuit interruptions 2. The switching frequency 3. The actual service time The actual conditions of use in terms of the frequency of operations, environment and severity of switching duty vary so much that it is impossible for the manufacturer to give detailed guidelines to the user concerning the frequency of maintenance.
