Answer / mayur m budh
Power per phase for a 3 phase ckt is given by
(V/Root3)*I*cosphi
3 ph power in a 3 phase ckt is given by
3*{(V/Root3)*I*cosphi}= Root3*V*I*cosphi
So for 2 phase it will be
2*{(V/Root3)*I*cosphi}= (2*V/root3)*I*cosphi

Answer / k.prakashchandra
Please examine the answer as V line =root3 Vph/2 +
root3Vph/2 and hence = root3 Vph. In 2 phase supply root3
does not come into picture as V1 and V2 are 180' apart..The
answer could be 2V x I x cos @ and V line= 2 V ph

I do wonder why current is present in neutral wire?i check single phase lead current feeding air conditioner...on its phase its current was 10A while same was 10A in neutral...as we know in neutral voltage is zero so if voltage is zero then how current appears on amp meter? my second observation is (just imagination)when I touch phase wire it give me shock but when i touch neutral nothing happens although as above its carrying current(amps) third but with same logic...as in simple Alternate current sine curve there is + and there is negative peak.means every time phase changing so how come every time same phase and same neutral stand (pardon for english mistakes)
Has someone here done a sizing for a generator (3 phase), its for a pumping station. If you have an example for standby/duty and both running (I) star delta (ii) Soft Starter.
