We have an automatic power factor controller installed and have six capacitors to control the power factor. the controller is switching on & off the capacitor in auto mode to control the power factor but when we monitor pf at the electricity board meter it is low i.e between 0.8 to 0.87 & @ controller it was unity. is it possible if the load is low?

if we appling capacitor at above rated what are looses and what will be happen
