← ScienceWhich consequence results when reactive power excessively stresses capacitor banks?
A)Increased transmission line phase angles
B)Dielectric breakdown within capacitance elements✓
C)Elevated transformer core hysteresis losses
D)Resonant frequency shift in filter circuit
💡 Explanation
Excessive reactive power leads to overvoltage; this causes dielectric breakdown because the electric field exceeds the capacitor's limit. This results in degradation or failure, therefore permanent damage occurs, rather than only affecting efficiency or frequency.
