Contrary to the fuseless configuration, where the units are connected in series, the unfused shunt capacitor bank uses a series/parallel connection of the capacitor units. The unfused approachwould normally be used on banks below 34.5 kV, where series strings of capacitor units are not practical, or on higher voltage banks with modest parallel energy.

When capacitors are connected in series, the total capacitance is less than any one of the series capacitors'' individual capacitances. If two or more capacitors are connected in series, the overall effect is that of a single (equivalent) capacitor having the sum total of the plate spacings of the individual capacitors.

We call such a configuration a capacitor. Start with both conductors being neutral. Take some charge from one conductor and put it on the other. The amount of charge moved from one conductor to the other is called the charge of the capacitor. (Contrast this with the actual total charge of the device which is still zero.)

Learn MoreEach 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.
As a general rule, the minimum number of units connected in parallel is such that isolation of one capacitor unit in a group should not cause a voltage unbalance sufficient to place more than 110% of rated voltage on the remaining capacitors of the group.
Depending on the application any of the following configurations are suitable for shunt capacitor banks: An individual fuse, externally mounted between the capacitor unit and the capacitor bank fuse bus, typically protects each capacitor unit.
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.
Shunt capacitor bank units that are connected in delta arrangement are typically utilized only at distributions voltages and are set with a single series group of capacitors rated at line-to-line voltage. With only one series group of units, no overvoltage happens across the staying capacitor units from the isolation of a failed capacitor unit.
Capacitor bank is usually controlled by the microprocessor based device called power factor regulator. Beside, segment installation practice demands protection for capacitor banks. In this case, capacitor banks are connected to the busbars, which supply a group of loads. What's good in this solution // No billing of reactive energy.
