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.

A generator operating at 50Hz delivers 1 pu power to an infinite bus through a transmission circuit inwhich resistance is ignored. A fault takes place reducing the maximum power transferable to 0.5 puwhereas before the fault, this power was 2.0pu and after the clearance of the fault, it is 1.5 pu. By theuse of equal area criterion, determine the critical clearing angle.
