Martzloff what quite clear about what plug-in (point of connection)
protectors can do to appliances. It was the very first conclusion in
his 1994 paper - that discusses where energy dissipates:
Conclusion:
1) Quantitative measurements in the Upside-Down house clearly show objectionable difference
in reference voltages. These occur even when or perhaps because, surge protective devices
are present at the point of connection of appliances.

What is necessary to protect plug-in protectors? What is necessary
so that plug-in protectors do not make appliance damage easier?
Earthing. And a 'whole house' protector properly connected short (ie
' less than 10 feet') to single point earth ground. Where is surge
energy dissipated when the effective 'whole house' protector is
earthed? Harmlessly outside the building. Then objectionable
differences do not exist in reference voltages.

Why do telcos all over the world not waste money on plug-in
protectors? They put their money where it does protection. Better
earth grounds and a 'whole house' type protector that costs
significantly less money. A protector is only as effective as its
earth ground.

Somehow that 1000 joules protector (that only used 333 and never
more than 667 joules) will magically make hundreds of thousands of
joules just magically disappear? I would say the same thing if my
profit margins were that excessive.
