    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.

  • Myth About SF6 Gas In Electrical Equipment

    Where is SF6 used? The following applications are known. For some of these most probably you haven’t heard of. For sound insulation in windows, In vehicle tyres, Is SF6 a health hazard? Pure SF6 is physiologically completely harmless for humans and animals. It’s even used in medical diagnostic. Due to its weight it might displace the oxygen in the air, if large quantities are concentrating in deeper and non ventilated places. Is SF6 harmful for the environment? It has no ecotoxic potential, it does not deplete ozone. Due to its high global warming potential of 22.200 (*) it may contribute to the man made greenhouse-effect, if it is released into the atmosphere. What is the overall contribution of SF6 used in the electrical equipment to the greenhouse effect? Less than 0,1 % ( see CAPIEL) and CIGRE). In an Ecofys study the contribution to the greenhouse effect in Europe is estimated to 0.05 % (*). People also search for
