Rp (primary) Resistance of the primary winding
Rs (secondary) Resistance of the secondary winding
Lp (pri. leakage) Leakage inductance of the primary winding
Ls (sec. leakage) Leakage inductance of the secondary winding
Lm (magnetizing) Magnetizing inductance seen from the primary winding
Np (primary) No. of turns of the primary winding
Ns (secondary) No. of turns of the secondary winding
The resistance is in Ohm and the inductance is in H. All the resistance and inductance values are referred to the primary.
The winding with the larger dot is the primary winding.
