Typical examples are motors, transformers, drives & fluorescent 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) as always 90 deg lagging with respect to active power as shown in figure 1, figure 2 & 3 show the flow of kW, kVAr and kVA in a network. Flow of active and reactive power always takes place in electrical installations. This means that the supply system has to be capable of supplying both active and 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 drops in the system
• Increase in the losses of transformers, switchgear and cables
• Higher kVA demand from supply system as given in figure 2
• Higher electricity cost due to levy of penalties / loss of incentives

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 quick & cost effective method of reducing and managing reactive power is by power factor improvement through power capacitors. The concept of reduction in kVA demand from the system is shown in figure 3. Heavy Duty Capacitors APP (Film + Foil) typeApplication
