Overhead service is an electrical service in which service-entrance conductors are run through the air from the utility pole to the building. See Figure 4. Taps allow different output voltages to be obtained from a transformer. Electricity is used in residential applications (one-family, two-family, and multifamily dwellings) to provide energy for lighting, heating, cooling, cooking, etc. As expected, I got single phase supply (with appropriate scaling) but got disappointed to see Unbalanced Phase currents on primary side. These Three Phase transformers offer consistent, smooth voltage transformation at 480VAC input. These transformers are put into an enclosure which is then filled with dielectric oil. "@type": "ListItem", It involves the use of a teaser transformer and the main one which are connected in such a way where you can achieve up to 90% conversion to the single phase.
