It is a known fact that in this era of technological advancement, efficient electrical systems integration is indispensable. In this regard, capacitor banks and power factor controllers are very important equipment primarily for industries that are targeting the enhancement of the energy utilization practices and cutting down on the cost of doing business. Capacitor banks are used to supply reactive power which is necessary for voltage support and for enhancing the power factor as well. Power factor controllers on the other hand provide a more flexible solution as they provide sufficient reactive power in accordance with the instantaneous demands of the electrical load. The control of this interplay improves the stability of power supply while saving as much energy as possible. Such technologies are unavoidable in the case of organizations sensitive to total energy costs.
