Bull****. A high series impedance can also provide effective protection.

Yes, high impedance can supplement protection when high impedance is
part of a system that also includes the only essential component in
any surge protection system: a low impedance (short, no sharp bends,
no splices, etc) connection to single point earth ground. High
impedance does not provide protection; can only supplement effective
protection. Effective protection is a low impedance connection to
single point earth ground.

Why is the 'whole house' protector so effective? Page 42 Figure 8
demonstrates what happens when a protector is too far from earth
ground and too close to the appliance.. Effective protector includes
separation (higher impedance) from the protected appliance AND a short
(low impedance) connection to earth ground. That low impedance
connection is essential. High impedance can only supplement the
protection and is not effective when that low impedance earth
connection does not exist.

Will a high impedance stop or absorb what three miles of sky could
not? Of course not. Obviously not. And yet some just know
otherwise. Will that silly little one inch part inside a plug-in
protector stop what three miles of sky could not? Of course not.

Without that short (low impedance) and essential connection to
earth, only then can a high impedance connection do something useful.
