Enter the transformer rating and losses to generate an efficiency curve and table. Add the % impedance to also calculate voltage regulation.

Losses are applied as entered, with no temperature correction, and assume linear (sinusoidal) loading at unity power factor for efficiency, with no adjustment for harmonic or additional stray losses. Voltage regulation is calculated at full load for lagging power factors, deriving %R from the load losses and %X from the entered % impedance.
