Calculate primary and secondary full load currents, and turns ratio for single-phase or three-phase transformers.
Turn Ratio:
\[a = \frac{N_1}{N_2} = \frac{V_1}{V_2} = \frac{I_2}{I_1}\]Single-Phase Primary Current:
\[I_1 = \frac{S}{V_1}\]Single-Phase Secondary Current:
\[I_2 = \frac{S}{V_2}\]Three-Phase Primary Current:
\[I_1 = \frac{S}{\sqrt{3}V_1}\]Three-Phase Secondary Current:
\[I_2 = \frac{S}{\sqrt{3}V_2}\]Where:
