Product informationCAuTIONDo not Exceed Transformer Ratings Transformersshould be operated only at the ratings specified on thetransformer nameplate Prolonged overload operationwill measurably shorten the projected service life of amineral oil-filled transformer Eaton’s Cooper Power™series PEAK™ transformers may help to extendinsulation life and can be operated at higher capacitiesthan traditional units while still exceeding ANSI®standard insulation lifeIntroductionThis manual has been prepared to assist competent techni-cians in the installation, operation and service of primary orsecondary unit- or open-type substation trans-formers.Substation transformers are designed for installation onthree-phase systems. All units are constructed for in-dooror outdoor mounting on a concrete pad with high and lowvoltage cables entering operating compartments throughenclosed sidewall mounted bushings (unit-type transform-ers) or through cover or sidewall mounted bushings (open-type transformers).Although every effort has been made to anticipate normalinstallation, operation and servicing problems, these instruc-tions do not cover all possible variations in equipment orapplication conditions. All possible installation, operation orservice contingencies are not discussed. If additional infor-mation is required, contact a factory representative.It is important that personnel using these instructionsbe fully acquainted with industry accepted high and lowvoltage safe operating practices and procedures. Theseinstructions are not intended as a substitute for propertraining or adequate experience in the safe operation of theequipment described.Read this manual firstRead and understand the contents of this manual and followall locally approved procedures and safety practices beforeinstalling or operating this equipment.Additional informationThese instructions cannot cover all details or variations inthe equipment, procedures, or process described, nor toprovide directions for meeting every possible contingencyduring installation, operation, or maintenance. For additionalinformation, contact your Eaton representative.Acceptance and initial inspectionIt is important that a thorough inspection of the transformerbe made before it is unloaded from the carrier.1. Ensure that all parts listed on the bill of lading arepresent.2. Before unloading the transformer, make an inspection todetect any signs of damage or mishandling. Locate anyaccessory parts that may have been shipped separately.3. If any damage is detected or shortages are noticed,write a brief description on the freight bill. Normally, thetransformer is shipped FOB point of manufacture, andit is the customer's responsibility to file a claim againstthe carrier. If the transformer was shipped FOB destina-tion, notify your factory representative. He or she will,with the inspector's report, take the necessary steps tofile a claim against the carrier.HandlingFor unloading, lifting hooks are provided near the top of thetransformer tank. Cable pull angles should not be over 30°from vertical. Otherwise, spreaders should be used to holdthe lifting cables apart to avoid any bending of the structureor lifting hooks.WARNINGDo not attempt to lift the transformer by placing a con-tinuous loop of cable or chain around the unit or liftinglugs Improper handling can result in death, severe per-sonal injury and equipment damageIf the transformer cannot be lifted by crane, it may beskidded or moved with rollers. When jacking a transformerto insert rollers underneath it, insure that at least two jacksare used and that two adjacent corners are raised simulta-neously and evenly to avoid warping the base. Jacks may beplaced only at the corners of the transformer base.Do not place jacks under cooler assemblies, valves, or sheetmetal parts. When using rollers, use as many as necessaryto distribute the weight uniformly. To pull, attach pulling eyesto the holes in the base at either end of the transformer.Do not attach pulling lines to moldings or other sheet metalparts of the transformer.StorageWhenever possible, the transformer should be stored at itspermanent location.The insulating liquid should be at its proper level and thegas space pressurized with dry nitrogen to approximatelytwo psig. Then it should be tightly sealed so that nomoisture or air can enter the tank. Periodic inspectionshould determine that the pressure gauge does not remainat zero, and proper liquid level is maintained at all times.The transformer should not be stored in the presence ofcorrosive gases (e.g., chlorine). Exterior surfaces of the trans-former should be maintained against rust and corrosion.Before placing a transformer into service after an ex-tendedstorage time, check fans, alarm and control circuits, and thedielectric strength of the insulating liquid.Quality standardsISO 9001 certified quality management system1SubStation tranSformer inStallation and partS replacement information MN202002EN JUNE 2016 |
