← TechnologyWhich outcome occurs when excessive current passes through an inductive power transformer's primary circuit?
A)Core material reaches saturation✓
B)Increased eddy current skin effect
C)Dielectric oil flash point decreases
D)Hysteresis losses linearly decrease
💡 Explanation
Core saturation is reached; excessive current intensifies the B-field of the core, and the *magnetic permeability* decreases, because the core's magnetic domains align, therefore limiting further increases in flux. Saturation occurs, rather than eddy currents increasing linearly, or changes flash point.
