why are distributed windings generally used in alternators?
what is the benefit of floating our DC source? if i have two floating DC source of which 1 has a ref voltage of -21VDC and the other of -18VDC. can it be connected in parallel to share a common ref voltage? if not, how do i make both sources to be of common ref voltage? tks

Whar is the KvA rating of 33Kv substation & actual kv rating of power generaating station.
A 400 V, 50 Hz, Δ connected synchronous generator has a field reactance of 0.1 Ω and armature resistance of 0.015 Ω. At full load, the machine supplies 1200 A at 0.8 pf lagging. Under full-load conditions, the friction and windage losses are 40 KW and the core losses are 30 KW. What is the machine’s overall efficiency? Ignore any field circuit losses.

relation between power station capacity and voltage level?
3 shows a 415 V, 3-phase generator supplying a 3-phase 415/110 V transformer. Draw the individual and combined impedance diagrams to a base of 10 kVA. Determine the system fault kVA and the fault currents at the 415 V and 110 V busbars for short circuit faults on the transformer input or output terminals. Work in p.u. values of impedances.
