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 single phase practical transformer rated 100 kVA, 12470 volts primary, 600V
secondary has a current and resistance of 0.101 of 220 kΩ. Determine the
reactive power in kVAR.
