Transformer Calculator. vs Southwire® Voltage Drop Calc Usage & Stats
Calculate the primary and secondary full-load currents of the transformer.
App also determines the turns ratio and type of transformer.
Select the number of phases ( 1Φ or 3Φ )
Enter the transformer rating and select the appropriate VA / kVA
Enter the primary and secondary transformer voltages
and you get
Primary full-load currents
Secondary full-load currents
Turns Ratio = N1 / N2 = V1 / V2 = I2 / I1

Southwire's voltage drop calculator will help you determine the proper wire size for an electrical circuit based on the voltage drop and current carrying capacity of an electrical circuit. Determines wire size to meet specific voltage drop limits or calculates voltage drop for a specific conductor run. When sizing conductors, calculations limits wire size to voltage drop and NEC ampacity. Southwire's Voltage Drop Calculator is designed for applications using AWG and KCMIL sizes only.
