Answer Posted / aravinda
consider voltage and current as phasors, angle between voltage and current is positive then leading (in case of capacitive loads) viceversa for lagging (in case of inductive load)
prevent lagging by parallal connecting capacitor banks or over excited synchronous motor
no need to prevent leading pf,
