Leakage Inductance
Several formulas have been derived for the calculation of leakage inductance. That originated by Fortescue^{(1)} is generally accurate, and errs, if at all, on the conservative side:
where L_{S} = leakage inductance of both windings in henrys, referred to the winding having N turns The greatest gain from interleaving comes when the dielectric thickness c is small compared to the window height; when nc is comparable to the window height, the leakage inductance does not decrease much as n is increased. It is often difficult to reduce the leakage inductance which occurs in highvoltage transformers because of leakage flux in spaces c. A small number of turns, short mean turn, and low, wide core windows all contribute to a low value of leakage inductance.
