That is really cool! What an excellent piece of work!
It's interesting that the regular xfmr model works for a shunted NST, or is
the shunt implicit in the 0.955 coupling constant?
Are these waveforms all with corona-type arcs, or are some with arcs to
ground?
No wonder it felt like I was kicked by a mule when Igor turned the coil on
when I was standing too close. Four amps or so is in the range of Taser
currents. I didn't lose muscular control and writhe on the ground, but it
does have the effect of causing one to involuntarily emit a long string of
loud and closely-spaced bad words. Defibrillation current is in the
neighborhood of 20 amps. Best we be careful.

Does this model measure up to scrutiny?

That procedure works very well here for steady state calculations at
full line voltage although the transient behavior with capacitor across
secondary and spark gap discharge can get very complicated and almost
chaotic.

The shunt results in large leakage inductance. Model it as a very
large inductor in series with the secondary.
For instance, if you have a 15kV, 30mA transformer, that implies that
the series impedance of the secondary is 15E3/30E-3 or 5 Megohms.
Using X = L *2*pi*f At 60 Hz, that's 13kHenry
