Ferranti effect,is as a result of long transmisson line
which is not heavily loaded.Since the lines are connected
parallel there is capacitance along the transmisson line as
such the receiving end voltage will eventually be more than
sending voltage.Mostly reactors are used to correct this
effect.

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
