I'm a little off topic here:
Does anyone know the "history" of hipot testing?
Say someone tells you to "hipot" your cable or wire harness at
1000VAC, measure the current, and decide if it's low enough. Where
did 1000VAC come from, and why is it AC?
I'm guessing it all started in World War Two building B17's and such.
Since AC was easy to make (you'd just use a transformer) people
probably picked it for the supply voltage. I'd also guess that 0.1 to
5.0 mA was the common current range because it was the lowest amount
your meter could measure (and it was just low enough not to kill you).
Does this sound correct?
Anybody know for sure?
