high-voltageswitchgear Network Monitor for 400kv

I am under the impression that one reason the high voltage distribution network is earthed is to dissipate electrical environmental effects (say, a lightning strike on the line). For long distance, high voltage distribution (275kV - 400kV as used in the UK), distribution is delta-connected.
