Automatic Power Factor Controller

Electronics and Telecommunication Engineering

The power factor correction of electrical loads is a common problem to almost all the industrial sector.Most of the loads draw a certain quantity of active power together with reactive power from the mains.The active power(kW) actually performs the work whereas the reactive power(KVAr) could be interpreted as an undesirable burden on supply.The increased flow of reactive power has various disadvantages such as overloading of power Source,higher voltage drops throughout the system,higher KVA demand,additional heating and loss of energy due to increased cable losses,etc.It is therefore essential that all efforts should be made to reduce the flow of reactive power in order to optimize system performance and achieve cost saving.Automatic power factor controller can be applied to industries,power system and house holds to make them stable and due to that the system becomes stable and efficiency of system as well as the appratus increases.The controlling of power is achieved by using a ARM7 controller.
