SecoGear – Installation, Operation and Maintenance Manual 12 of 56Excellent maintenance is essential for the reliability and safetyof any electrical equipment:• Maintenance programs must be designed for the specificapplication, well planned and carried out consistentwith both industry experience and manufacturerrecommendations.• The local environment must always be considered, includingsuch variables as ambient temperatures, extreme moisture,number of operations, corrosive atmosphere, major insectproblems, and any other unusual condition or abuse ofthe application.One of the critical service activities, sometimes neglected,involves the calibration of various control devices. Aproper calibration monitors conditions in the primaryand secondary circuits, sometimes initiating emergencycorrective action, such as opening or closing circuit breakers.In view of the vital role of these devices, it is importantthat a periodic test program be followed. GE recommendschecking all significant calibrations at an interval ofone to two years, until you have accumulated enoughMaintenance3. Although the provided interlocks reduce some of therisks, the individual’s actions while performing serviceor maintenance are essential to prevent accidents. Eachperson’s knowledge, mental awareness, and planned andexecuted actions often determine if an accident will occur.The most important method of avoiding accidents is forall associated personnel to carefully apply a thoroughunderstanding of the specific equipment – from theviewpoints of its purpose, its construction, its operation –and the situations that could be hazardous.All personnel associated with installation, operation, andmaintenance of electrical equipment, such as power circuitbreakers and other power handling equipment, must bethoroughly trained, with periodic retraining, regarding powerequipment in general, as well as the particular model ofequipment with which they are working.Instruction books, actual devices, and appropriate safety andmaintenance practices such as OSHA publications, NationalElectric Safety Code (ANSI C2), National Electric Code, andNational Fire Protection Association (NFPA) 70B ElectricalEquipment Maintenance must be closely studied and followed.During actual work, a supervisor should audit practices toassure conformance.experience to select a test interval better suited to theindividual requirements. The interval between periodicchecks will vary depending upon the local environment,the type of device, and the user’s experience.Some devices can be adequately tested using test sets.Specific calibration instructions on particular devices aretypically provided in the vendors’ documentation. However,these manuals cannot include every possible part that couldrequire attention, particularly over a very long service periodor under adverse environments. Maintenance personnel mustbe alert to deterioration of any part of the supplied switchgear,taking actions as necessary to restore it to serviceable status.Industry publications of recommended maintenancepractices such as ANSI/NFPA 70B, Electrical EquipmentMaintenance, should be carefully studied and appliedin each site’s formation of planned maintenance.Visit geindustrial.com for the latest publications.Some customers may require additional assistance fromGE in the planning and performance of maintenance.GE Industrial Solutions offers onsite services to performmaintenance or provide technical assistance.The performance and safety of all equipment may becompromised by the modification of supplied parts or theirreplacement by non-identical substitutes. All such designchanges must be qualified to ANSI/IEEE Standard C37.59.Maintenance personnel should methodically keepwritten maintenance records as an aid in future serviceplanning and equipment reliability improvement.Promptly report any unusual experiences to GE.
