Answer / arvind kumar pal
Power factor is nothing but angle between voltage and current. As the angle increases means pf lags result high requirement of currents which creates voltage drops. Therefore it can damage the equipments as equipments are designed as per their voltages

The disadv of lag pf is that it causes the voltage regulation
to increase towards maximum value due to which the o/p volt
decreases.
volt reg= (V no load - V full load)
= IR cos phy - IX sin phy
in case of lag pf the current is lagging i.e I<-phy
so , the volt reg
= IR cos phy + IX sin phy is more
