Transformer and genrator PF depends on the nature of
connected load ( Motor ), But motor has its own fixed Power
factor

Therefore Transformer and genrator capacity shown in KVA (
Without PF ) and motor Capacity shows in Kw ( with power
factor )

Answer / gunnam santosh

kw=kva*pf
powerfactor depends on loads, transformers and generators
are not designed for a specific loads,the powerfactor of
these tf and gen are know by knowing the powerfactor of the
load which is being supplied by them.so their ratings are
given in kva

Answer / rm

GENERATOR PRODUCES POWER & MOTOR CONSUMES POWER

Answer / arun kumar.k

Generator is produsing the power supply and it is flow of
electron it in form of VA
AND they have own rating and they have own power factor

In motor we calculating the efficiency
>efficiency it always in watts or workdone
>And WE cant relate kva to the load
LOad it s only carry the kw Because load only utilizing
the power and we want to exepcet the load only efficiency
or Work done
>load is only for power utilizing

y we use neutral,all r told its used to for closed path..k its a just used to closed path,in a transmission line y we put same conductor used n both phase and neutral..if we use less than phase conductor in neutral mean we ll reduce cost its right r wrong..if we use mean any problem occur in transmission line..
