How does grounding the neutral at a service protect it from lightning or lightning induced voltage or current? To me if a lightning strike induces a surge on the power lines therefore inducing a surge on the xfmr and into the house,the damage could come from the overvoltage of the phase conductors as easily as an elevated voltage on the neutral.The grounding of the neutral at the service for a lightning strike and the bonding of the neutral to the ground return paths for fault clearing purposes are obvious.but even if everything was grounded properly and there were no difference in potential between all grounded noncurrent carrying parts of an electrical system is it not safe to say that damage resulting from a lightning strike could be from the rise in the phase voltage? Most everything I read partaining to lightning usually has this line in it......Was it grounded properly?
