to find phase displacement of 3 winding transformer, first of all consider the core construction of core and prepare sample model of core and draw a circle around the core which touches the end of the core arms. now core arm devides circle into three parts and measure the angle between two arms which is phase difference.

how we can come to know that motor winding resistance which showing by DMM is right or wrong???is there any chart or something that we will compare & check???
