IEC 60931-3 1st Edition, August 1, 1996
Shunt power capacitors of the non-self-healing type for a.c. systems having a rated voltage up to and including 1 000 V Part 3: Internal fuses
Additional Comments: BILINGUAL
Published By:International Electrotechnical Commission (IEC)
Scope and object
This part of IEC 931 applies to internal fuses which are designed to isolate faulty capacitor elements or a capacitor unit, in order to allow operation of the remaining parts of that capacitor unit and the bank in which the capacitor unit is connected. Such fuses are not a substitute for a switching device such as a circuit-breaker, or for external protection of the capacitor bank or any part thereof.
The object of this part of IEC 931 is to formulate requirements regarding performance and testing and to provide a guide for co-ordination of fuse protection.
