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 single-phase transformer has 500 turns on the primary and 100 turns on the secondary. The mean length of the flux path in the core is 2.0 m and the joints are equivalent to an air-gap of 0.1 mm. The value of the magnetic field strength for 1.21 T in the core is 400 A/m, the corresponding core loss is 1.8 Watts/kg at 50 Hz and the density of the core is 7850 kg/m3. The cross-sectional area of the core is 0.0187 m2. If the maximum value of the flux density is to be 1.21 T when the nominal rated voltage is applied at 50Hz, calculate the magnitude of the primary current, in amperes, if a load current of 135 A is being supplied at a lagging power-factor of 0.85.
