The DC voltage rating for high voltage insulation does not
take into account RF coupling of high voltage AC Signals
through the insulation to grounded objects. It is found
that high voltage wire insulation must be de-rated by
approx. a factor of four for the high voltage frequency
levels used. For instance, to run a 10KV triangle wave at
1KHZ requires insulation on the test cables with a DC
rating of at least 40KV.
