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 transformer is connected to a 660 V supply . The voltage to turn ratio of the
transformer is found to be 1.1 and secondary is 440V. Determine a) N1 and N2 b) Cross-
sectional area of the core if the maximum flux density is 1.4T.
