They yet exist: SGTC's throwing nice sparks, i.e. David Rieben's "Green
Monster" or my friend Fritz Egli's "Xanthippe". On November 4, 2012 some
test runs of Xanthippe were performed in Fritz' motorbike show-hall.
Some movies were taken by Andi Saile, and combined by Kurt to a video,
which now is uploaded to YouTube. See:
...the first video:
We feel, the coil to be well tuned nowadays, and operating close to the
components limits, running smoothly. A longer debottlenecking and
enhancing process, realized by Fritz and Andi, preceded the result. Part
of the coil data:
Wallplug VA: ~12 kVA
HV Xfrmer: 2 PT's VKe30 / 16 kVac
Rotary: SRSG at 200 BPS
Cap: Maxwell's 120 nF / 70 kV
Toroid diameters: 126.5cm x 32.5cm (50" x 12.8")
Overall height of TC: 224cm (88")
Is the rotary synchronous to the line? That is, are your breaks at the
45 degree points so all 4 per cycle are at the same voltage?
...there are 4 stationary electrodes at 90 mech. degrees, and 2 rotating
electrodes at 180 mech. degrees of the full circle, giving a bang each 90
electrical degrees as well. The phase is adjusted, in order to have 4 equal
bangs of the same voltage, by means of a John Freau type phase shifter.
