Nitesh the current you take with fluke meter is running current not a full load current. All the 6 lead draw same amount of current. But that current is a running current.

Why only 58%

[@electricalwithabhishekjoshi]

1/1.732 ka percent nikalo.. its 57.7%
Phase current is 1/1.732 time of line current. Video mein bataya hai.

[@SandeepSharma-xy3oj]

Sir, Why take only 33% in star. When voltage reduce the current increase.?
Practically we see when motor starting time current take more the full load. Plz reply..

[@electricalwithabhishekjoshi]

Sandeep, it is true that when voltage increases current decreases and vice versa. I think you have doubts that voltage will decrease in star then how current will decrease as they are inversely proportional. Right?
But Sandeep, you are comparing phase voltage with line current.
In star, phase voltage will reduce not the line voltage.
Hope you got the point..
