SRSG graph



Hi All, 

Jeff just posted the KVA Effects SRSG Timing Chart as part of another post.
The greatest energy at the cap is the V & I crossing at 45 and 225 degrees.
If you plotted values for current and voltage, these two points would show
the greatest power available when the current and voltage are 90 degrees
out of phase. 

If I were to set an SRSG for 120bps, it seems I would want to set the gap
to fire somewhere after V-peak heading towards the 45 degree point. Coilers
have reported their coils run best when the SRSG firing point is set a few
degrees after the peak (myself included). 

When we actually run our coils, the closer we bring the V & I waveforms
together (pulling charing current up), the higher the power will be made
available, and also, higher up on V-peak should be the best running point
(i.e, 20 degrees or whatever it turns out to be). 

Anyway, this stood out to me in the chart as to the reason SRSG's run well
when set after V-peak. Does this sound about right?

P.S., I would have again posted Jeff's chart but I deleted the email
already and couldn't find it in my url history - sorry about that).
