Hi,

Please see a very common way to measure the leakage inductance of a flyback transformer:

Short circuit all the secodary windings together, and measure the inductance of the primary winding. You then get the leakage inductance of the transformer.

hey. terry. thanks a lot.

by the way, there are two ways to short the secondary windings: 1:short all the secondary windings to one point; 2: short all the secondary windings separately. please see the attached pics. could u tell me which one is correct or more accurate? thanks...
