Answer Posted / iamdon
When the linear dimension of a machine is varied by x times,
its output is varied by x*x*x*x times
its loss(Fe and Cu each) is varied by x*x*x times and
its temperature is varied by x times.
provided rest parameters are not varying.

i am an maintenance engineer. one distribution board have 5 feeder. recently its ELR trips frequently, but it take some times after trip( 10min,20min..)but 3 feeder no load. two feeder only loaded. i checked one feeder IR value all values are above 50Mohm.but B phase to Earth is only 9Mohm.any problem about low value

- two pumps must work with them at the same time but if the first pump start the second pump must delayed for some time to start also , with motor rated power = 90 KW and rated voltage = 380 V and rated power factor = 0.85 lag please draw the power and control circuit for it and determine all circuit components parameters that you use it
