Which 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.
