Transformer Design Calculation Excel [top] -

Worked example: 5 kVA, 230/115 V, 50 Hz Inputs (choose these cells in Excel)

Go to Data > What-If Analysis > Goal Seek . Set cell "Regulation %" to value "3" by changing cell "Current Density". This automatically optimizes wire size. transformer design calculation excel

cap T cap E cap V equals the fraction with numerator 1 and denominator 4.44 cross f cross cap B sub m a x end-sub cross cap A sub c cross 10 to the negative 8 power end-fraction =1/(4.44 * B3 * B4 * B5 * 10^-8) (B3=Freq, B4=Flux Density, B5=Core Area). Primary/Secondary Turns: cap N sub p =PrimaryVoltage * TEV Secondary ( cap N sub s =SecondaryVoltage * TEV * 1.05 Worked example: 5 kVA, 230/115 V, 50 Hz
