What meant by lagging and leading? When if they are
occurred what preventive methods should be taken?

Answer Posted / a.balakrishnan

Basically Three types of load are there..
1.Resistive load
2.Inductive load
3.Capacitive load
Resistive load always having unity power
factor.So we do not consider that type of loads.
In Inductive load Having Lagging power
factor,so we must improve the power factor.For this
improvement we can choose capacitor,Synchronous Motor
connected in parallel.These Loads give the Leading
current ,so it is compensate the lagging current...
