3.6. A 60-KVA, 4800/2400-V single-phase transformer gave the following test results: 1. Rated voltage is applied to the low voltage winding and the high volt- age winding is open-circuited. Under this condition, the current into the low voltage winding is 2.4 A and the power taken from the 2400 V source is 3456 W. 2. A reduced voltage of 1250 V is applied to the high voltage winding and the low voltage winding is short-circuited. Under this condition, the current flowing into the high voltage winding is 12.5 A and the power taken from the 1250 V source is 4375 W. (a) Determine parameters of the equivalent circuit referred to the high volt- age side. (b) Determine voltage regulation and efficiency when transformer is operat- ing at full-load, 0.8 power factor lagging, and a terminal voltage of 2400 V. (c) What is the load kVA for maximum efficiency and the maximum effi- ciency at 0.8 power factor? (d) Determine the efficiency when transformer is operating at 3/4 full-load, 0.8 power factor lagging, and a terminal voltage of 2400 V.

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.
