Capacitor standards specify that capacitor units shall give not less than the rated reactive power at rated sinusoidal voltage and frequency, and not more than 110% of this value, measured at 25 °C uniform case and internal temperature.
The recommendations for the capacitor part are given in IEC 60143-1:2004. Specific information about protective equipment can be found in Clause 3 and 10.6. This second edition cancels and replaces the first edition published in 1994 and constitutes a technical revision.
Guidelines for capacitor fusing are given in IEEE Std C37.48. In distribution capacitor banks, group (line) fusing, individual capacitor unit fusing, internal fusing, or a combination may be used. Group fusing involves the use of a single fuse in series with all of the capacitors in that phase.
NOTE—This table does not apply to internally fused capacitors. Typical recommendation is not to exceed 100 times nominal capacitor unit current for internally fused applications. For frequently switched banks (switched daily or greater) and for back-to-back switching, the peak capacitor unit current should be held to lower than the 100 000 value.
The continuous-current rating of switchgear used for capacitor bank switching may be a factor in choosing the capacitor bank size.
For internally fused capacitors with unbalance protection, the guidelines for the unbalance protection settings are the same as for substation capacitor banks. Guidelines for capacitor fusing are given in IEEE Std C37.48.
