Check all of the tap jumpers for proper location and for tightness. 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. There are instances when a tree must be trimmed or removed without prior notification. Part 2 will address installation procedures for dry- and wet-type transformers, the latter being fully assembled. Serious injuries and even fatalities have occurred when I found createlogodesign.com by searching the internet, and decided to try them out without a first hand referral. 373-6, Deflection of Conductors, and referenced in Sec. How do I identify distribution and transmission structures? But opting out of some of these cookies may affect your browsing experience. Ensure that all grounding or bonding systems meet NEC and local codes. 4, on page 44, and when all enclosure hardware is tightened so panels do not vibrate. There are different ways in which transformers are installed and used as part of a commercial building electrical system. Dry-type transformers have sound levels that are somewhat 4 0 obj North America | April 5, 2018. So confident am I in their workmanship and design skills that I will be coming back - and I am delighted with the results. Standard transformer tests performed for each unit include the following: * Polarity for single- and 3-phase units (because single-phase transformers are sometimes connected in parallel and sometimes in a 3-phase bank); * Phase relationship for 3-phase units (important when two or more transformers are operated in parallel); * Excitation current, which relates to efficiency and verifies that core design is correct; * No-load core loss, which also relates to efficiency and correct core design; * Resistance, for calculating winding temperature and [I.sup.2]R component of winding losses (usually not required on 600V class units); * Impedance (via short circuit testing), which provides information needed for breaker and/or fuse sizing and interrupting rating and for coordinating relaying schemes; * Load loss, which again directly relates to the transformer's efficiency; * Regulation, which determines voltage drop when load is applied; and. See my site logo at. The basis for proper pruning is that each limb removed from a tree is removed either where it joins another limb or at the trunk. Duke Energy uses aerial application of herbicides in areas with high brush density and rough terrain and that are hard to access to control trees and other vegetation that can pose power outage threats. hkO0ibv*JmG[$ Necessary cookies are absolutely essential for the website to function properly.

(Most of the information in these standards also can be applied to liquid-filled transformers.). The cookie is used to store the user consent for the cookies in the category "Other. Duke Energy Transmission procedure documents are the property of Duke Energy. down from each of the ends of the long sides. What can I do in a transmission right of way? Aerial maintenance applications can be completed much more quickly than manual spraying, reducing crew exposure to physical hazards in the right-of-way environment. In addition, to avoid problems, a civil engineer should be consulted for guidance on the above matters. When planning the installation, you should select a location that complies with all safety codes yet does not interfere with the normal movement of personnel, equipment, and material. Once the transformer has been located on its permanent site, a thorough final inspection should be made before any assembly is accomplished and the unit is energized. If you see a downed line, immediately contact Duke Energy. it windows (first story) 10 10 When placed inside or on top of a building, you must consider structural capabilities because a transformer represents a highly concentrated load. When transformers are installed for parallel operation, their rated voltages, impedances, and turn ratios ideally should be the same and their phasor relationships identical. But be careful here: Before applying this voltage, check with the manufacturer's manuals. See Table 1 for typical dry-type transformer ratings, dimensions, and weights. createlogodesign provided very impressive artwork for our projects and does so in a very timely, efficient manner. Another consideration for indoor distribution transformers is the type of load: linear or nonlinear. These cookies ensure basic functionalities and security features of the website, anonymously. Do not install washers between the terminal lugs and the termination bus bar as this will introduce an added impedance and will cause heating and possible connection failure. <>>> The majority of our pruning and cutting occurs during planned maintenance. [ILLUSTRATION FOR FIGURE 2 OMITTED]. If appropriate, supports should be used so that the transformer enclosure is not crushed when the unit is lifted. Webrequirements. Air intake openings in the wall may be necessary or a larger minimum surrounding This is especially true if bronze or other type material is used for the nuts/bolts. These terminations should be attached to the cables as specified by the termination or cable manufacturer. For example, trees can grow into the electrical equipment or fall across power lines, causing outages. 7. We really liked two of them, and asked him to amalgamate them. gz&E6;ZdEv;z~gx 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. When people identify downed lines or trees touching power lines and act wisely, it minimizes the risk from trees contacting power lines.

Duke Energy 3-Phase Padmount Transformer Concrete Foundation Specifications For Mecklenburg County, NC Only July 2009. For example, if the transformer is installed in a quiet hallway, a definite hum will be noticed. Therefore, it's advisable that you seek guidance on this matter from an engineer knowledgeable in seismic supports and the associated code requirements. (If the power transformer has CT circuits, they should be closed.) The location of a transformer relates directly to how noticeable its sound level appears. Copyright www.CreateLogoDesign.com. Hint: Duct Tape to the Rescue. When does Duke Energy obtain permission to trim or take down a tree? If the load-side voltage is high, tap connections above 100% of line voltage must be used to lower the load voltage. 3 0 obj Line side (unmetered) and load side (metered) conductors shall not occupy the same raceway or enclosure.
