Hello,
I use relay for an AC(115V RMS) load, relay switches on/off both line and neutral.
Schematic is below.
I want to measure spike voltage on relay contact when switch off.(I can see spark on relay contacts)
The load current is 4A RMS, pf:0,85
I did not measure spike voltage pin 8 of relay, I am confused which point should be referance to measurement?
Because the relay both switches line and neutral.
I have tried measurement spike on pin 8 referenced to pin 12, pin 5 ,pin 9 but I could not see any spike.
After relay switches OFF, pin 5 and pin 8 are float points, so I think I could not measure.
I would be glad if you share ideas..
