A very important function of the grounding in a multi-grounded wye distribution system is the dissipation of surges which are caused by lightning strokes near the distri-bution system.

Therefore, the most important thing we care about is the potential of the PE wire, not the potential of the N wire, so repeated grounding in a TN-S system is not a repeated grounding of the N wire.

We can create a system grounding that reduces voltage stress at the cost of large fault current magnitudes. However, in such a system the faulted circuit must be de-energized immediately to
