1. A 1000-VA 350/140-V transformer has been tested to determine its equivalent circuit. The results of the tests are shown below. Open-circuit test Short-circuit test Voc = 235 V Vsc = 20.1 V loc = 0.57 A Isc = 9.6 A Poc = 34.3 W Psc = 42.7 W All data given were taken from the primary side of the transformer. Evaluate the equivalent circuit of this transformer referred to the low-voltage side of the transformer.

A:

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.
