Answer Posted / jothiprakash.t
Power factor is cosine angle between Voltage and
current.Suppose a alternator of capacity 5000KVA is
operated at unity powerfactor,then it means it can supply a
maximum load of 5000KW load (KW=KVA*P.F).If a same
alternator is operated at 0.8 p.f ,then it can deliver only
4000KW Which means the alternator was loaded maximum.To do
maximum loading of alternator then its power factor has to
be unity or close to unity.
If power factoris above unity, then -ve KVAr itself acts
as a load causing more current to draw from mains Which
leads to heating and also losses.
