As shown in (5), the leakage reactance in the zigzag … SpletEven when using a type of magnetic shield with closed magnetic path structure, the leakage cannot be controlled perfectly. The flux leakage control depends on the coil structure. Also, the usage of vertically wound coil involves polarity, and the leakage flux is influenced by intensifying/weakening directions against the signal.

Splet29. jul. 2024 · The turn-to-turn faults (TTF) are also inevitable in split-winding transformers. The distorted leakage field generated by the TTF current results in large axial forces and … SpletGenerally we think of leakage fluxes as flowing at least partly in the air and not just being confined to the core, where they link both the primary and secondary windings. This flux next to the windings that is associated with the proximity effect is in fact leakage flux.

Splet29. jul. 2024 · The turn-to-turn faults (TTF) are also inevitable in split-winding transformers. The distorted leakage field generated by the TTF current results in large axial forces and end thrusts in the fault windings as well as affecting other branch windings normal operation, so it is of significance to study TTF of split-winding transformers.
