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...

In a large office how do we calculate required number of light fittings, assuming fittings are 4x18W or 2x36W fluorescent fitting ?
we all know voltage is a force(emf), and the force always devides if 2 or more than2 loads are there but why does the voltage remains same is parallel, it must devide na ???

I have a drawing of a wound rotor induction motor for a crane. This crane motor has 5 forward speeds & 5 reverse speed implemented of course with different amount of resistance for each speed setting selected. What has got me scratching around is the fact that 8 of the 10 speed selections switch in uneven (unbalanced) amounts of resistances on each of the 3 connections to the motor's rotor.Can this be possible? I would have assumed this would produce unbalanced rotor currents and therefore vibration in the motor. I would greatly appreciate anyone's comments on this. Many thanks, Confused.
