2.1 Switching-in capacitor banks Capacitor bank switching is often affected by overvoltages and transient overcurrents. The worst case occurs if a capacitor bank is switched-in when other banks are already connected (so-called back-to-back switching). This is because the amplitude and frequency of the inrush current can be very high.
