Duke Energy to invest $36B on power projects by 2026. The larger pieces of wood are cut to the length of firewood and stacked or consolidated at the edge of the right of way for the property owner's use or disposal. In seismic areas, the stability of the unit with respect to turning over must be evaluated, whether placed outside or in a building, because a transformer usually has a relatively high center of gravity. Only line clearance qualified personnel should perform tree work around or adjacent to power lines and electrical equipment. A protective plating or compound that prevents surface oxidation on the aluminum terminals is usually applied at the factory.

The majority of our pruning and cutting occurs during planned maintenance. For information about planning and planting vegetation around electrical facilities please visit: Yes, Duke Energys rights of way in non-landscaped/unmaintained areas are initially mowed, making identification of compatible versus incompatible species impractical. A number of manufacturers require that insulation resistance testing be successfully completed prior to the transformer being placed in service for the warranty to be valid. These considerations should be taken into account, as well as the use of sound absorbing materials on walls (for low frequency sound) and vibration isolation pads under the unit. Some transformer manufacturers recommend that the cable size be based on an ampacity level of 125% of nameplate rating. [ILLUSTRATION FOR FIGURE 2 OMITTED]. Pruning trees around power lines should only be attempted by qualified professionals. I highly recommend that if you are looking for a graphic designer than createlogodesign is your first port of call.

Till date we have designed more than 5,000 business logos. Air intake openings in the wall may be necessary or a larger minimum surrounding The weight distribution should be studied by examining the inside of the transformer enclosure for dry-type units. You should arrange for an insulation resistance test to be carried out to make certain that no windings are grounded. Watch Jana's Story. These practices are approved by internationally recognized tree care associations and are referred to as Integrated Vegetation Management (IVM). Baeza is a principal and senior electrical engineer at TLC Engineering for Architecture in Miami. WebDuke Energy Transmission DECorp: Duke Energy Midwest . You should note, though, that transformers serving large harmonic loads can produce a higher audible noise. For linear load applications, transformers should be selected with lower core losses. USA, North Carolina: U.S. electricity company Duke Energy announced it has allocated investments of $25 billion to be spent on grid modernization and $11 billion for expanding renewable and natural gas-fired power generation over 2017 to 2026. You should consider this when planning the unit's installation. These terminations should be attached to the cables as specified by the termination or cable manufacturer.

Who should trim or cut trees around power lines? The first set of logo ideas were terrific. There are NEMA standards for transformer sound and depending upon the kVA rating of a unit, the sound it produces must be under a certain decibel level. This may include personalization of content and ads, and traffic analytics. endstream endobj startxref Transformers, along with other power distribution apparatus, remain a fundamental component in electrical systems distribution for commercial buildings. If our attempts to notify you are unsuccessful, work will proceed without further direct notification.

Is Duke Energy responsible for cleanup after trimming trees or weather events? Some microprocessor-based electronic devices may not be able to withstand the voltage. If this data can be used, the extra cost to carry out tests can be avoided without sacrificing the quality of the transformer. Duke Energy does not prune trees for light levels or pattern. 373-6, Deflection of Conductors, and referenced in Sec. 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. Before applying any voltage to the transformer, you should make sure that the tank for wet-types, or the enclosure and core assembly for dry-types, is permanently and adequately grounded. Any control circuits, if any, should be checked to make sure they function correctly. 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 Clearance Rules for Distribution , 4 of 10 Clearance Rules for Distribution ; Clearance Rules for Distribution , 5 of 10 Clearance Rules for Distribution ; Clearance Requirements, 6 of 10 The Duke Energy Progress (DEP) Distribution Construction Standards are available on the My Duke Energy Contractor Portal. 1 A Minimum of 4 Original Drafts for your Logo.
