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...

Please help me regarding my one concern. - During earth pit testing we noticed that the Clean earth pit and dirty earth pit showing continuity (Resistance value - 5ohm) . I want to know that if both earth pit have separate location and there is not internal looping between PIT then why such continuity is showing on it . Because of this issue the field side all earthing point showing short. In PLC panel we are providing two types of earthing cable which is coming from separate earth pit (Clean and Dirty earth pit) because of earth PIT showing short our PLC is not complying spec . please help regarding this issues.
