Peter,
The metrics we use to specify the more complex surge waveshapes are
only a modest improvement over the answer a red one to the what car
do you drive? question.
The ring and possibly 8/20 (part of the combination) waveshapes
have current reversals, which complicates matters.

Thank you.
In one case, the output was after the CDN. In the other, the CDN was not in
the circuit. I will ask for calibration screen captures with and without
the CDN on both cases. This could prove informative.

Good morning.
I'm wondering if others have experienced cases where different
manufacturers' surge test equipment (ANSI/IEEE C62.41 ring and
combination waves) with nearly identical open-circuit voltage and
short-circuit current calibrations have led to very different results. In
these cases,
