Transformer Voltage Calculator

Transformer Voltage Calculator. φm = Vp / Np kf Since same flux links the primary and the secondary V s / N s = k φ m f and φ m = V s / N s kf Hence V p / N p kf = V s / N s kf Therefore Vp / Np= Vs / Ns and Vp / Vs = Np / Ns Relationship between Turns ratio and current For an ideal transformer the input power is always equal to the output voltage Hence V p.

V s is the secondary winding voltage How to calculate transformer turns ratio? The transformer turns ratio n is calculated as \( n = \dfrac{ V_{p} }{ V_{s} } \) Where V p is the primary winding voltage V s is the secondary winding voltage Example 1 Calculate transformer full load current Calculate the secondary full load current of a a 200 kVA 11 kV to 420 V step down.
