Capacitor bank protection design consideration white paper
Bank stability is achieved when a single fuse operation does not result a single unit exceeding 110% of its rated value. If the 110% threshold is exceeded, the bank is considered at risk and should be removed from service. In other words, a bank should generally be designed to accommodate at least one fuse operation and still stay operating
