WebTransformers are used in the power system in order to step up or step down the voltages. In the transmission end the voltage is stepped up and in the distribution side the voltage is stepped down in order to reduce the power loss (i.e.) copper loss or I 2 R loss. The current decreases with increase in voltage. Web5 de jun. de 2024 · A transformer is an electrical device designed to transfer electrical energy from one circuit to another at the same frequency.

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. WebTransformers use electromagnetic induction to change the voltage of alternating currents. The voltage and current changes can be calculated, as the power transfer is constant.
