Answer / nithi

if power factor is leading ,this will leads the following.
system voltage increases-more pressure on
insulation-equipment life reduces-insulation break down-
over heating-over fluxing-core saturation-noise in core-
core over heating-may lead to ferroresonance(when resistive
loss is small)this will further complicate the situation-
harmonic production-increased THD-harmonic resonance-
penalty from EB-malfunction of control equipments & switch
gears-if overall system p.f. is leading,result in ferranti
effect-loss of power system costly apparatus-increased
losses-reduction in overall efficiency.
but actually,this will not happen in the power
system due to the presence of varios controls like
FACTS,shunt reactor,series reactor,synchronous condenser..

Answer / karthick

due to lead of power factor it causes the voltage to increase
hence, lows the value of current ,,, due to high voltage it
causes the equipment to damage

Answer / mayuri baradkar

actually the power facter should be leading. because of
leading power factor kva capacity will increase. this will
reduces the power consumsion.so we have to preffer the
capacitor bank in any industrial areas.which will not lagg
the power factor.
