Hi - those are very nice looking sparks and arcs. If you are claiming that there is 3 million volts shown in your video then please can you say something about how it was estimated or measured?

[@MarcelGallaun]

Thanks a lot! It's only a rough estimation. The longest arcs were around 1-1,5m. The typical dielectric strengh of air is 3kV per mm. So for 1m the voltage would have to be around 3MV if I'm not mistaken.

Thank you, that is certainly one way to look at it. The books and papers I have read also show a figure around 3kV/mm for dielectric strength of air. However, where the e-field is made non-linear by things like small conductors and break-out points, the overall voltage can't be estimated that way. For example, it turns out that a spark gap around 1m long between points or needles breaks down at about 600kV which calculates as 0.6kV/mm for the whole gap. Also, a 4:1 toroid would need to be about 1.2 metres diameter to ‘contain’ 1MV without discharges to the air all around it. Further, once an arc is ‘struck’ it might need about 500kV/m to keep it ‘alight’. Bottom line is, high voltages like this are very difficult to measure or even to estimate but I don’t think many experimenters with HV experience would have claimed 3MV on the evidence you show! For myself, I might estimate a range of 500kV-1MV. But they are still very nice arc pics, nicely presented!
