Please excuse my rather dim question but I'm very familiar with homebrewing all manner of DC powered circuits but when it comes to AC..I'm in the dark, sorry.
I'm building a firing circuit for oilfield perforating. We will have AC (Generator) so I'm using a variac to slowly build-up voltage to fire the cap/pcord.
I have a AC voltmeter downstream of variac and have an AC ammeter but I've been told that you can't wire it in the circuit in series as you would in a DC circuit?
It is an old simpson panel meter and I'd like to wire it in but I don't want to fry it accidently.
My wiring sequence is:
AC>switch>variac>switch(safety)>voltmeter>cable to well
Does this make sense?
Thanks!
