what happan when ac power transmitted in unity power factor
Answer Posted / karthik
i dnt think transmitting at unity pf. we can produce
voltage in that we normelly used to gen at 0.9 leading pf.
we couldnt go beyond this limit bcz of over rotor heating.
if we use this power for more number of motors and
lightings which is having low power factor the resultant
current drawn from the gen station ll be lagging only..
power factor purely depends on load only. at gen station we
can go upto alternator allowed range of leading pf..
if we consider this question as in the distribution station
if we try to deliver power at unity pf we may fail to judge
the load pf at each instant.. it may vary time to time..
even we further concentrate and done it we can minimise the
losses in line and billing of industry may reduce bcz of
UPF @ they r charged by KVAh tariffs...
