Initial setting for sync phase angle on an RSG
I don't have an RSG my self to try this on, but I had a thought.
You temporarily replace the stationary electrodes on your RSG with metal
wire the electrodes to a small battery with a series resistor so that current
would flow when the rotating electrodes bursh past the stationary brushes. Then
connect a dual trace scope so that the first trace is connected to your 110
and the second trace connected between the RSG electrode and resistor?
You should see a nice sine wave on the top trace, and a pulse indicating
RSG fires on the bottom allowing you to adjust the phase angle rather
without having to put your hands close to HV.
Think this would work???
