A capacitor bank which has a plurality of capacitor units, in which each capacitor has a plurality of electrical capacitor elements, and the capacitor units are divided into a plurality of groups of capacitor units. The arrangement has a plurality of group monitoring units, with one of the group monitoring units associated with each group of capacitor units. At least one of the group monitoring units is configured so that it monitors the respective group of capacitor units for a failure of a capacitor element in one of the capacitor units of the group and, when such a failure of a capacitor element is detected, transmits data which describe this failure of the capacitor element to a monitoring receiver.

Method of monitoring a capacitor bank for failures

A fuse element and a method for manufacturing the same are provided whereby the fuse element contains an active response part which is formed by an elongated fuse metal strip having at least four metal sub-strips. At least two of the metal sub-strips are parallel and the sub-strips are defined by two elongated recesses within one or two elongated fuse metal strips. The two recesses are provided in serial alignment along the respective fuse metal strip having leading and trailing parts for electrical connection of each fuse element. The elongated fuse metal strip can be reinforced by an elongated dielectric base layer made of polymer material. Accordingly, performance of such a fuse element can be increased and manufacturing costs can be decreased. The fuse element can be applied to a plurality of capacitor sub-units being integrated in housings and submerged in a cooling and insulating liquid within the housing.
