I believe the principal culprit is the extreme magnetic field that surrounds
the conductors when the surge protector operates rather than the current in the
PE conductor. This field can generate high voltages in adjacent and nearby
low-voltage conductors such as

It seems to me that TC 108 documents really devise surge protection
component tests rather that complete equipment tests and

In my opinion, surge suppression in a power strip or in a product may protect
the local environment from overvoltage, but may create additional overvoltages
elsewhere on the system.
Many surge suppression techniques place a momentary short-circuit on the mains.
