Concept explainers

Single Phase Transformer

A single-phase transformer is a type of power transformer. It is an electrical device that accepts converts the single phase alternating power into single phase alternating power. In this power conversion the voltage is stepped up or down. If the voltage is stepped up, the current will be stepped down and if the voltage is stepped down, the current will be stepped up.

Question

A 20-kVA, 586 V load is to be supplied by an ideal step-up autotransformer from a 400-V source. Find the current in the common winding. Use two decimal places for final answer if necessary.
