SpletThere is a flux leakage which means that not all of the flux produced by one winding will link the other winding. 2. Primary and Secondary windings have resistances which means that the applied voltage (source voltage) v1 is NOT the same as the induced primary voltage e1; that is, v1 ≠ e1. Similarly, v2 ≠ e2. 3. Splet01. dec. 2024 · Leakage flux generated in the power transformers cause stray losses in metallic parts of the transformer. Stray losses largely affect the transformer hot spot which leads to thermal failure. It is necessary to mitigate the impact of leakage flux on metallic parts by employing magnetic shunts and eddy current shields.
