Dangerous high voltage will be present within the transformer enclosure. * Applied and induced potentials, which verify dielectric strength. YUMPU automatically turns print PDFs into web optimized ePapers that Google loves. After applying proper torque, you should wait a minute or so, and then re-tighten all bolts to the specified torque. When changing taps, the same changes must be made for all phases. Develop a procedure for inventory of all tools, hardware, and any other objects used in the inspection, assembly, and testing of the transformer. Mounting the unit on a platform that has less mass than the transformer will make the platform serve as a sounding board, just like the body of a violin. endstream endobj 53 0 obj <>/Metadata 20 0 R/OpenAction 54 0 R/PageLayout/OneColumn/Pages 50 0 R/StructTreeRoot 32 0 R/Type/Catalog/ViewerPreferences<>>> endobj 54 0 obj <> endobj 55 0 obj <>/Font<>/ProcSet[/PDF/Text/ImageC]/XObject<>>>/Rotate 0/StructParents 0/Tabs/S/Type/Page>> endobj 56 0 obj <>stream After installation, you should check the output voltage of the transformer.

There are different ways in which transformers are installed and used as part of a commercial building electrical system. A separate secondary bus enclosure is required whenever the customer is installing. * Insulation power factor, which is done at initial installation and every few years thereafter to help determine the aging process of the insulation. % If the structure is wooden and 30 to 40 feet tall with or without transformers attached, it is typically a distribution pole. There should be no attempt to handle a transformer in any other position. The revisions were done quickly and to my specifications, and often I was provided multiple versions from which to select. 847 0 obj <>stream The MIA South Terminal expansion was designed with about 50 transformers with similar intent as the stadiums but a more diverse group of loads for the 208 Y/120 V 3-phase, 4-wire system, which also included lighting loads, signage, telecommunication, security systems, and other loads part of this building project (Figure 1). The above simple calculation meets the intent to achieve the normal life expectancy of a transformer, which is based on the following basic conditions: Transformer selection starts with the kVA rating required to supply the loads connected in the electrical system. They are very professional, and the team knows their craft. The insulation resistance test should be conducted immediately prior to energizing the transformer or the beginning of the dielectric test. This type can be installed in areas with corrosive or dirty atmospheric conditions where it would be impossible to use a ventilated-type transformer.

In addition, there are other specific requirements based on the transformer type, such as weatherproof enclosures for dry-type transformers installed outdoors or a transformer vault room for oil-insulated transformers installed indoors. Structurally speaking, it's generally wiser to place a transformer as close as possible to a column. Duke Energy Transmission procedure documents are the property of Duke Energy. Larger units will have provisions for lifting from the base frame or from clamps at the top of the core. Following are some of the transformer types available in the industry along with a few of their characteristics: Ventilated dry-type transformers are ventilated by air, use larger space for clearance, and use different insulating materials to augment the dielectric strength of the air.
