Which reliability issue appears first due to transformer excitation asymmetry from unbalanced capacitor bank switching?

💡 Explanation

Asymmetrical capacitor switching during power factor correction causes a DC voltage offset, leading to *core saturation*, because it shifts operation away from the designed zero-flux point; therefore, the core overheats due to increased losses, rather than changing winding properties uniformly.
