  • Transformers: Leakage flux , Exciting current and core

    Jan 12, 2015The secondary leakage flux is proportional to the secondary current. There is a resulting reactance voltage drop in the secondary winding. Both the primary and the secondary leakage fluxes reduce the secondary terminal voltage of the transformer as the load increases. The leakage flux of. a transformer can be controlled by the type of core used.
