Failed capacitor elements, as well as …
Protection of Capacitor Bank
Unit fuse protection limits the duration of arc in faulty capacitor units. This reduces the risk of major mechanical damage and gas production, protecting neighboring units. If each unit in a capacitor bank has its own fuse, the bank can continue operating without interruption even if one unit fails, until the faulty unit is removed and replaced.
