Most capacitor fuses have a maximum power frequency fault current that they can interrupt. These currents may be different for inductive and capacitively limited faults. For ungrounded or multi-series group banks, the faults are capacitive limited.
An outdoor capacitor fuse is designed for fusing individual capacitor units in standard outdoor equipment, specifically for voltage classes of 2.8, 5.5, 8.3, 15.5 and 23 kV, and currents of 8 kV, 15/20 kV and 25 kV, 100 A. It also has a high-energy capability for use in outdoor capacitor banks with many parallel capacitor units, with voltage classes of 5.5-18.2 kV and currents of 15-43 A.
This fuse is used for capacitor banks with a large number of parallel capacitors. It can be used on applications with essentially infinite parallel stored energy, as long as sufficient back voltage can be developed to force the current to extinguish.
A full range capacitor fuse is a current-limiting, non-disconnecting capacitor fuse, rated for voltages from 1.2 to 23 kV and continuous currents from 25 to 100 A. It is used for fusing individual capacitor units in standard outdoor equipment, for voltage classes of 8 kV, 15/20 kV, and 25 kV.
Eaton’s Cooper PowerE series bus-mounted expulsion-type capacitor fuse provides highly reliable, economical protection for capacitor banks where medium-energy-interrupting ability is required. See Table 1 for electrical ratings. The fuse tube is constructed of bone-grade fibre overwrapped with epoxy-bonded filament-wound fiberglass.
For high voltage capacitor fuses, this is generally defined as 8.3, 15.5 or 23 kV, the distribution system maximum voltages. Other voltage ratings may be available for special applications. When a capacitor fails, the energy stored in its series group of capacitors is available to dump into the combination of the failed capacitor and fuse.
