Answer Posted / raju karmakar
The insulation level of earthed cable is less than uneath cable. If the system voltage is 33KV than the mark on cable will be 33/33KV on uneath cable and 33/19KV will be on earthed cable. It means than during fault in R-Phase the voltage of other two phases will rise to 1.732 times of system voltage. If the rated voltage is 19KV than the insulation of earthed cable will damage. But the unearth cable will stand.
