Hi Rich:
Thanks for insight on this. I think your
as the only
possible failure mechanism of the SPD is fail-open. However, I
think the assumption that SPDs can only fail open is flawed.
For 6.2 (protection of equipment users), I do not see how the 1000 VRMS
barrier provides any degree of safety protection if it can be bridged by
an SPD in normal use
gh the SPD. (Of course, there
is some very small current due to the
stray system capacitance to earth through the mains transformer.)
DISCUSSION
My principal question is why a safety standard would go to the
trouble of
calling out an
chose to use a 200 volt SPD. So, in normal use, the
effective isolation would be 200 volts. If the SPD fails short, the
isolation is zero. Since the equipment has no connection to earth,
protective earth has no role in the operation of the SPD.
DISCUSSION
My principal question is why a safety standard
voltage, the
isolation system is not a safety isolation, i.e, is
not a basic insulation.
Nevertheless, because the external circuits are
subject to transient over-voltages, the isolation
system must withstand such over-voltages. Therefore,
the isolation system is subject to an electric
strength test
.

The apparent contradiction that I was trying to describe can be
summarized as follows:

Hipot test values are based on expected transients. The concern with the
