HOW VFD USED IN ENERGY SAVING

Answer Posted / suresh

VFD – variable frequency drive..
VFD is useful in energy saving because it reduces the
motor speed as demand decreases.When the speed is reduced
the power consumption Will also reduce because ,
Power = (speed)3 {cube of speed}
For example if the speed is reduced to 80% of the maximum
value the power consumed will be reduced by 50%
Power consumed = (0.8)3 = 0.512 = 51.2%
