← TechnologyWhich outcome occurs when high-frequency harmonics circulate within a power transformer core?
A)Increased core hysteresis loss and heating✓
B)Reduced magnetizing inductance and efficiency
C)Elevated dielectric stress and insulation breakdown
D)Enhanced transformer voltage regulation
💡 Explanation
When high-frequency harmonics circulate, increased eddy current and hysteresis losses occur in the core because the rate of magnetic flux reversal escalates significantly elevating core temperature. Therefore, core hysteresis loss and heating results, rather than improved voltage regulation, reduced inductance or insulation breakdown without sustained load.
