Answer / deepak24

for a definite area of core a circle has smallest circumference. so circle has smallest mean length of copper. so cost will reduce for copper for circular winding.

Answer / harshad patel

The excessive leakage flux produced during shirt circuit and over load and developed mechanical stress for The coil.
On circular coil these force are radial and these is no tendency for The coil to change its shape.
But on rectangular coil The force are perpendicular to The conductor and tends to deform The coil in circular form.

Answer / shammas shaz

economical benefits

Answer / suri

The flux linkage is more in the circular coil. just imagine
yourself.

Will it be OK to connect a 5MVA 33/6.6kV Ynd11 Transformer to a Star connected Motor. Or on other words connecting a Delta to a Star. I have another 30MVA 33/11 Dyn11 and would it be practical to convert it to Dd0 consequently converting the Voltage Ratio to 33/6.35kV Dd0.
