Each phase consists of 12 units or 36 units for a three-phase bank. Each unit should be rated 9.96 kV and 667 kvar. For a fuseless bank, capacitor units are only connected in series (illustrated in Figure 10); they are never placed in parallel like an externally or internally fused capacitor bank.
The optimum arrangement for a shunt capacitor bank depends on the best usage of the available voltage ratings of capacitor units, fuses, and protective relaying. Nearly all substation units are linked wye. Distribution capacitor units, nevertheless, may be linked wye or delta.
When designing a capacitor bank, many factors must be taken into consideration: rated voltage, kvar needs, system protection and communications, footprint and more. These factors govern the selection of the capacitor units to be used, along with proper grouping of these units.
Parallel energy has typically been viewed as a non-issue for internally fused capacitor banks because the current limiting fuses are commonly used. However, fuse sizing/rating must still be considered when designing the unit to ensure fusing selection is appropriate to handle discharge energy into the shorted element through its fuse.
