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.

2) What are the effects of saturation on the magnetizing current, no-load power
losses, and efficiency of a power transformer?
3) What are the advantages and disadvantages of operating a power
transformer with little or no saturation?
