Source Impedance Calculator

The source impedance of the transformer is required in order to simulate the transformer "sagging" under load.

Supply voltage: (VP) The voltage primary supply into the transformer, normally 110/115/220/230/240 volts.

Winding resistance: (RP) The measured resistance of the primary winding.

Off-load voltage: (VS) The measured voltage on the secondary of the transformer before any load is applied.

Winding resistance: (RS) The measured resistance of the secondary winding.

Resistance for simulation: R.equiv = ((VS/VP) x RP) + RS
