Discuss Single phase circuit on 3 phase system calc in the Electrical Forum area at ElectriciansForums.net

Hi,

I have a query about calculating current in a 3 phase system. So a 22kw load in 3 phase assuming a power factor of 0.8 would be 22000/(1.732x400x0.8) = 39.69A

and say a 7.2kw load on a single phase supply would be 31.30A if you simply use ohms law.

But what happens when you calculate the current in a single phase circuit on a 3 phase system. I.e a single phase load connected to L1 (or L2 or L3) and neutral? Do you use the single phase current calc or the 3 phase current calc?. and why?
