The uniqueness of this scenario lies in the decision to install the capacitor bank at the 11 KV voltage level, even though the factory receives power from the grid at a higher voltage level of 132kV, with an approved connection capacity of 12 megawatts.
Low voltage capacitor bank installed as harmonic filter. It is the end user's responsibility to protect equipment from the effects of typical disturbances on the supply network. Capacitor switching transients on the distribution system can be in the range 1.5–1.8 per unit peak with an oscillation frequency in the range 300–1000 Hz.
High voltage capacitor banks are composed of elementary capacitors, generally connected in several serial-parallel groups, providing the required electrical characteristics for the device.
The data used to select an automatic capacitor bank are the reactive power Q (kVAR), the rated voltage, the number of operations, and the value and number of steps.
Composition of LV capacitor banks A distinction is made between fixed value capacitor banks and “step” (or automatic) capacitor banks which have an adjustment system that adapts the compensation to the variations in consumption of the installation.
The primary objective of this capacitor bank is to enhance the power factor of a factory. Local regulatory standards dictate that the power factor for bulk supply connections must be maintained at 0.9 or higher.
