Capacitor banks provide an economical and reliable method to reduce losses, improve system voltage and overall power quality. This paper discusses design considerations and system implications for Eaton’s Cooper PowerTM series externally fused, internally fused or fuseless capacitor banks.
To improve the energy storage capacity of ceramic capacitors and promote their application in more environments and a wider range, ceramic powders with such local polymorphic polarization configuration were selected to prepare MLCC prototype devices by tape-casting process and screen-printing technique.
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.
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.
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. Therefore, when analyzing a fuseless capacitor bank, the number of internal series sections is an important consideration.
There is a consensus that the energy storage performance of capacitors is determined by the polarization–electric field (P – E) loop of dielectric materials, and the realization of high Wrec and η must simultaneously meet the large maximum polarization (Pmax), small remanent polarization (Pr) and high Eb.
