I'm a bit confused with the figure below (extracted from here: http://www.allaboutcircuits.com/vol_2/chpt_10/7.html). If I'm not mistaken, the phase current and line current of a star-connected system should be the same. However, as shown in figure below, they look different because the line current contains (w,5w,7w) whilst the phase current contains (w,3w,5w,7w,9w). Is it correct? Thanks.
