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.
The IEEE Std 18-1992 and Std 1036-1992 specify the standard ratings π of the capacitors designed for shunt connection to ac systems and also provide application guidelines.
Abstract— High voltage shunt capacitor banks (SCB) are widely used on power systems. The installation of shunt capacitor banks has beneficial effects such as the voltage regulation and the reduction of the losses of active power to be transmitted.
High voltage capacitors are used in equipment made to improve Power Factor, and provide voltage /VAR support. The capacitors use time proven, low loss, highly reliable GE all film dielectric systems. Dielektrol® VIIa Non-PCB insulating fluid is used in our state of the art dielectric fill process.
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.
For certain capacitor bank configurations some faults within the bank will not cause an unbalance signal and will go undetected. For example: a) rack-to-rack faults for banks with two series groups connected phase-over-phase and using neutral voltage or current for unbalance protection; and, b) rack-to-rack faults for certain H-bridge connections.
