Benefits of Improving reactive energy management
1. Increase in available power
2. Reduction in Line Current
3. Increase in KW/Litre by optimum loading
(With Sample Work out)


Principle of Reactive Energy Management
All electrical loads which operate by means of electromagnetic field effects, such as motors, transformers, fluorescent lighting etc., basically consume two types of power, namely, active power and reactive power

Active Power (kW) It is the power used by the loads to meet the functional output requirement. It is also called Actual Power, Active Power or Working Power

Reactive Power (Kvar)
It is the power used by the load to meet its magnetic field equipments and the requirements of magnetic losses. (Eg. Transformers, Motors,etc)
The reactive power is always 90 degree out of phase with respect to the active power.

Apparent Power (kVA) is the vector sum of Active Power (kW) and Reactive Power (kVAR). It is also known as the ‘demand’

Effects of Reactive energy
-It is now clear that both active and reactive energy are necessary inputs in all electrical systems.
-But the reactive power has certain negative aspects which result in increased cost of electrical systems and also drop in the efficiency of system operations.
-This increased flow of reactive power results in the following impacts. 1)Overloading of Generator.
2)Increased I2R losses leading to additional heating and loss of energy.
3) Higher KVA Demand on the system.
