Original poster: Vardan <vardan01@xxxxxxxxxxxxxxxxxxxxxxx> Hi, I will disagree :o))It is like you car just ran out of gas on the highway but the motor is still spinning. If you keep it in gear (secondary in place) the car will use the spinning energy to move it just a little further down the road.
It you put the car in neutral all the spinning energy will be lost into heat inside the engine as to motor takes a little longer to come to a stop. No big deal either way. Probably twice the power is burnt of in the gap, but that normally will not hurt anything.
On the other hand if you ran a DRSSTC (unlimited primary drive energy) without a secondary. The primary will resonate up immediately until something blows!!!
In the case of the SISG, I go from 34.81 Arms to 55.61 Arms!!! So high efficiency solid state coils should probably never be run without the secondary!!
The spark gap will be brighter and louder, but a lot of that is due to the energy simply being dissipated "faster" in the gap without the secondary in place. The current is not higher nor the voltage. It just bangs faster! It also has about twice the energy in the bang too that normally would have gone to the secondary.
Basically, the "high" resistance of the conventional spark gap spoils the "Q" of the system and it rings down fairly quickly before much extra RMS current shows up.
Cheers,
Terry

The mechanical equivalent of this is putting your car into neutral with no load on the engine and then holding the gas pedal to the floor. Sure, it will run for awhile, at redline, but it's certainly not something I would imagine anyone doing for very long or even doing at all.Dr. Resonance ----- Original Message ----- From: "Tesla list" <tesla@xxxxxxxxxx> To: <tesla@xxxxxxxxxx> Sent: Monday, October 02, 2006 10:55 AM Subject: Re: first coil progress...Original poster: Mddeming@xxxxxxxIn a message dated 10/2/06 2:33:15 A.M.

Concerning my belief that running a complete primary circuit with no secondary would increase the RMS current through the cap - Terry's simulation and response takes me by surprise! I had always heard that this was not a safe thing to do, and reasoned that by removing the secondary and eliminating any quenching, the peak current remains the same, but you just get more pri-sec trades in the same bang-interval, so wouldn't this raise the RMS current? Or are the gap losses so huge that what isn't transferred to the secondary is mostly burned up in the gap? Snip.... Hi Gary,I'm not sure I follow how you get more pri-sec trades with the secondary removed. Did you mean more damped oscillations in the primary per bang?Matt D.
