When fault occur phase to ground voltage is √3 time the normal phase to ground voltage. … Unearthed cable has more insulation strength as compared to earthed cable. When fault occur phase to ground voltage is √3 time the normal phase to ground voltage. So if we used earthed cable in unearthed System, It may be chances of insulation puncture. So unearthed cable are used. See more In HT electrical distribution, the system can be earthed or unearthed. The selection of unearthed or earthed cabledepends on distribution system. If such system is earthed, then we have to use cable which is … See more Earlier the generators and transformers were of small capacities and hence the fault current was less.
