The primary weakness of the shunt capacitor units is that their reactive power generation is relative to the square of the voltage, and accordingly when the voltage is low and the electrical system needs them most, they are delivering the least amount of the reactive power. The capacitor unit is the essential element of a shunt capacitor bank.
These standards specify that: of rated terminal RMS voltage and a crest voltage not exceeding rated RMS voltage, taking into account harmonics but omitting transients. to 110% of The shunt capacitor units should also be able to withstand 135% of nominal current.
The shunt capacitor element can be made for a comparatively high voltage since the external fuse can clear a high-voltage fault. Application of capacitor elements with the greatest possible voltage rating will lead to shunt capacitive unit with the lowest number of series groups.
The main disadvantage of SCB is that its reactive power output is proportional to the square of the voltage and consequently when the voltage is low and the system need them most, they are the least efficient. 2. THE CAPACITOR UNIT AND BANK CONFIGURATIONS The capacitor unit, Fig. 1, is the building block of a shunt capacitor bank.
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.
