Answer / benu

kva=kw/pf,with low pf,kva will be high,insulation cost in generator and transformer+cu loss in transmission line will rise and efficiency will come down

Answer / rajivgandhi

should be reduce the losses ..

Answer / koti

above answer is partially correct i.e, at low pf the kw output is low and is due to inductance and capacitance elements of ckt but not harmonics

Answer / ghulammohyhuddin

power factor control mager demand form electrical city

because actual lode between appearance lode is power factor

Answer / purushottam kumar

for constant power and terminal voltage ,if power factor is low current drawn is more ,so more lose ocour ,regulation is poor, conductor size increased than with high power factor

Answer / sudhakar g

Power factor is imp bcoz....ex: If we have an panel that
will give the o/p of 300KW but if we dont maintain the
powerfactor by using APFCR it will give the o/p of 240KW
only....by maintain the powerfactor by using the APFCR we
can get (0.98%)....power factor means something lagging and
leading in power due to harmonics...
