WebJan 4, 2024 · The U.S. Department of Energy proposed higher energy-efficiency standards for three categories of distribution transformers to improve the resiliency of the U.S. power grid, lower utility bills and cut carbon-dioxide emissions. According to the DOE, this proposal is a strategic step to diversify transformer core technology. Distribution transformers are normally located at a service drop, where wires run from a utility pole or underground power lines to a customer's premises. They are often used for the power supply of facilities outside settlements, such as isolated houses, farmyards or pumping stations at voltages below 30 kV. Another application is the power supply of the overhead wire of railways electrified with AC. In this case single phase distribution transformers are used. danby visitor centre
