is the power delivered by 1 no. of 3 phase system equal to the power delivered by 3 nos. of 1 phase system? Assuming same voltages and amps ratings

Sorry, what does the abbreviation "no." stand for in your post? Thanks.Jasper12 said:is the power delivered by 1 no. of 3 phase system equal to the power delivered by 3 nos. of 1 phase system? Assuming same voltages and amps ratings
I'm assuming if you replace the word "no" with "set(s)", the question will make sense.berkeman said:Welcome to PF.

That all depends on how they are connected, and to what. It's not just "volts" and "amps", there are network and phase considerations. Please provide a more detailed description of the circuits, bonus points for a schematic!Jasper12 said:is the power delivered by 1 no. of 3 phase system equal to the power delivered by 3 nos. of 1 phase system?

Care to expand on any of that?Gavran said:A three-phase system can serve as three single-phase systems and it can be said a three-phase system can deliver three times as much power as a single-phase system.
For high-leg delta three-phase systems this can not be said.
Gavran said:In North America when delivering 3 phase power using a high-leg delta there is not the same line-to-neutral voltage on all three phases and that means the power delivered by a single-phase can not be the same for all three phases and all three phases together can not deliver three times as much power as any of them.
Yes, but you have more of them, so it's not the same amount of copper.Gavran said:the same conductor size
