A vast majority of Electrical loads in low industrial installations are inductive in nature. Typical examples are Motors, Transformers, Drives, Flourescent lighting. Such loads consume both Active and Reactive Power. The Active Power is used by the load to meet its real output requirements whereas Reactive Power is used by the load to meet its magnetic field requirements. The Reactive Power ( inductive) is always 90 deg. lagging with respect to the Active Power. it is thus a reality that the flow of Active and Reactive Power always takes place in Electrical installations. his means that the supply system has to be capable of supplying both Active & Reactive Power.
The Supply of Reactive Power from the system results in reduced installation efficiency due to Increased current flow for a given load.Higher voltage drop in the system. Increase in losses of Transformers, Switchgears and Cables. Higher KVA demand from the supply system. Levy of penaltie
by the Electrical supply authorities
It is therefore necessary to reduce & manage the flow of Reactive Power to achieve higher efficiency of the Electrical system and reduction in cost of Electricity consumed. The most cost-effective method of reducing and managing Reactive Power is by Power Factor improvement through Power Capacitors.
Due to changing nature of modern electrical installations if has now become necessary to use various types of fixes and variable power capacitors to achieve desired power factor improvement.
The methodology followed to achieve a consistently high power factor under modern application conditions is referred to ac "REACTIVE POWER MANAGEMENT" therefore involves proper selectionand use the following products.
• Power Capacitors
• Automatic Power Factor Correction systems
• Detuned Harmonic Filters
