The Contractor will submit complete

The Contractor will submit complete test procedure and test forms/test sheets for every factory test, atleast three months before starting the factory tests. Design values will be produced on the test forms /test sheets. Further test procedure and test forms/test sheets will also be provided for site tests wellbefore the commencement of the tests at site.The test reports of the transformer to be supplied shall include test reports of all the components to beinstalled on the transformers i.e. bushings, bushing C.Ts, Buchholz relay, pressure relief device, oiland winding temperature indicators, on load tap changer etc.All electrical parts such as circuit breakers, contactors, relays or similar devices shall be separatelytested in accordance with applicable IEC standards before assembly of the transformer and the con-trol cubicle.All motors shall be factory tested to establish their electrical and mechanical integrity. Tests shall con-sist of at least those defined as routine tests by the appropriate IEC standards for each type of motorAssemblies: All electrical assemblies other than motors shall be tested at the factory, including thecompletely assembled and wired terminal boxes, to establish their electrical integrity and proper oper-ability. Tests to be made shall include: Low frequency dielectric tests on power and control circuits, including wiring and equipment in ac-cordance with IEC Publications. ontinuity of control circuit wiring and of the grounding of non-current-carrying parts of equipment. Operational tests under insulated service conditions to assure operability of all equipment and de-vices, proper mechanical functioning of all parts of the assembly and correct mutual functioning ofinter-related components.Tests shall be carried out to indicate proper installation and functioning of buchholz relay for operationwith slow and fast evolution of gas in the power transformer.Tests shall be carried out on the transformer for proper operation of on-load tap changer and its con-trols and accessories. Tests shall be carried for the proper operation and indications of the on-load tapchanger and its accessories when operated either manually or electrically.Tests shall be carried out on each group of cooling equipment to check that cooling equipment canoperate continuously with auxiliary supply at -10% of the rated supply voltage for the fans.Test shall be made for proper calibration and functioning of oil temperature indicators and windingtemperature indicators.Each shipment of transformer oil shall be tested in accordance with IEC 60156 and other relevant IECStandards.9.26 Drawings, Technical and Descriptive Data9.26.1 GeneralFore each type of transformer, Bidders shall supply the following with their bid: Technical data sheet Detail list of performed type test. Copy of required type test reports Dimension drawing and layout, to clearly describe the construction and operation of the equipment Catalogues and manuals
