← ScienceWhich risk increases because of intense localised magnetic fields induced during transmission?
A)Ferrite core saturation occurs✓
B)Dielectric transformer breakdown initiates
C)Increased corona discharge appears
D)Conductor ohmic heating dominates
💡 Explanation
Ferrite core saturation risk increases because high currents cause exceeding magnetic fields; this initiates irreversible magnetization changes. Core permeability consequently plummets, rather than dielectric breakdown which involves voltage exceeding capacitance, and saturation has magnetic causes.
