    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.

The guidance is considered good practice but is not compulsory. You may find it useful in deciding what you need to do. However, the guidance may not be directly applicable in all circumstances and any queries should be directed to the appropriate enforcing authority. 2 This document contains information for the attention of both managers and technical staff concerning the electrical risks (see para 5) that can arise from the use of high-voltage and low-voltage oil-filled electrical distribution and other switchgear which was manufactured prior to 1970. The term 'switchgear' includes : oil-switches, oil-isolators, oil- switch fuses and, in particular, oil circuit-breakers (see Appendix 1 for definitions). Advice is given on the precautions which should be taken to eliminate or control these risks. (Because of the nature of this subject many of the terms used will be more easily understood by elec...
