Leakage Reactance - an overview | ScienceDirect Topics Gavrilović OBE, in Electrical Engineer's Reference Book (Sixteenth Edition), 2003. 32.7.6 Turn-off behaviour. At turn-off, the switching action of the valve excites an oscillation between the transformer leakage reactance and the circuit stray capacitances. This oscillation cannot be critically damped but the degree of voltage overshoot can be minimised by the correct choice of values for ...
