Leakage Reactance

Applications of Leakage Inductance
... Leakage inductance can be an undesirable property, as it causes the voltage to change with loading ... Leakage inductance has the useful effect of limiting the current flows in a transformer (and load) without itself dissipating power (accepting the usual non-ideal transformer losses) ... are generally designed to have a specific value of leakage inductance such that the leakage reactance created by this inductance is a specific value at the ...
