Distribution transformer circuit diagram. The invention of a practical efficient transformer made ac power distribution feasible. A distribution transformer or service transformer is a transformer that provides the final voltage transformation in the electric power distribution system stepping down the voltage used in the distribution lines to the level used by the customer. Figure 1 shows a typical distribution circuit and table 1 shows typical parameters of a distribution circuit. Shawn tracy via flickr a feeder is one of the circuits out of the substation.

The schematic diagram at the upper right is perhaps easier to analyze as the delta connections can clearly be seen. Explain and interpret information found on transformer name plates. Indentify the schematic symbols of potential and current transformer. Product literature and application advice were provided by abb.

Identify transformer polarity using dot and conventional labeling. Transformers are capable of either increasing or decreasing the voltage and current levels of their supply without modifying its frequency or the amount of electrical power being transferred from one winding to another via the magnetic circuit. Compare and contrast the performance of three phase transformer connections. 240 volts delta secondary.

List characteristics on these devices and explain how. A system using distribution transformers was demonstrated. High voltage power substation on swan island photo credit.
