Advantages Of Fuse-Less Capacitor Bank
Disadvantages Of Fuse-Less Capacitor Bank
1) Any earth fault in the bank, unit, such as bushing fault, insulation failure between a tank and live part of the capacitor, should be cleared immediately by tripping of circuit brake associated with this bank as there is no provision of any fuse.
2) For replacement of any capacitor unit, only identical spare is required. It cannot be managed by available standard capacitor unit. So, there must be sufficient stock of identical capacitor units available at a site which is an extra investment.
4) Sophisticated relay and control system are essential for fuseless capacitor bank. The relay system of the bank should also be capable of tripping the circuit breaks associated with it in the event of input power failure to the relay.
