Answer Posted / nishad

Above answer almost correct. Eventhough I would like to add
something.
In Load current there are two components 1> active
components which is the current consuming by the custmer.
2> Recative components which is the current responsible for
the system, lead to lag / lead.
well, If reactive power is increased, PF will be lag. means
the system will carry more current for the disered out put
the same of unity PF. So our losses will increases like
more bigger size cable, breaker we need.as well as our
power system will over loaded. as reasult CU loss & Iron
loss will increase. so try to avoid that stage.
If active powre increase, then also system will over
loaded. to avoid that, share the load of particular system
