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.

down a balanced 3-phase, 200V supply to a balanced 3-phase, 100V supply? Explain with circuit and
phasor diagrams. Calculate also the maximum kVA that can be supplied from this connection.
