Answer / melwyn dsilva

x=pie*r2
wherex=185
185=3.142*r2
r2=185/3.142
r2=58.9
r=7.7
then dia=15.4

Answer / sreenu

Cable size represents one core area. First convert the area
into dia(a). The cable diameter is calculated by adding
sleeve, armour, outer sheeth dia to 3*a +1/2*a for 3 1/2
core cable. Exact size can be seen in cable manufacturers
catalogue.

Answer / sakthivel

your power cable size is 185 sq mm

now diameter of the cable is

d= square root of area of the cable* 4*7/22
my answer in your question

d=square root of 235.45

can you tell me/show me, how to manually synchronize 2 DG. preferred with video.

Can u explain whether any possible to happen like that. In Phase SEquencemeter is showing correctly in both substations. How is it happen. Explain me.Explain me communication signal will produce Phase difference on this case.
