WebbHow does leakage flux occur? This leakage flux is produced due to the primary amp turn (m.m.f) existing points a & b. This flux ϕl1 is in phase with primary current I1 and induces an e.m.f el1 in primary winding similarly the secondary amp-turns c and d, leakage ϕl2 which is linked with secondary winding only (not linked with primary winding). Webb22 dec. 2024 · Obviously, "phase" is a pair of opposite coils where the current at both poles flows in opposite directions.
