Transformer Calculators
Turns ratio, voltage transformation, power, impedance matching, VA/watts and ratings — the full language of transformers. Seven complete tools, all live.
01
Turns Ratio
n = Np/Ns, plus voltage & current ratios.
Live 02Voltage Transformer
Solve for primary or secondary voltage.
Live 03Transformer Power
Apparent (VA) and real (W) power.
Live 04Impedance Transformer
Reflected impedance Zs = Zp / n².
Live 05VA ↔ Watts
Convert with power factor.
Live 06Transformer VA Rating
VA = V × I per winding.
Live 07Primary / Secondary Voltage
Vs = Vp / n from a given ratio.
