Trying to understand how the insulation resistance test works
this is how I think it works, i maybe right or maybe wrong?????????

bascially, your shorting circuiting neutrel and phase.
Sending 500v down the cable (If no voltage no current)
So the tester sends out a current, then reads the return Current and calculates the leakage

then using ohms law, calculates the resistance

and this is a DC test?


is this right?
