Voltage problems of Eza(BGA) to the medium voltage grid

In the protection relay is an HV cables angle of 9 ° at a time of 0, set 2 sec. At least according to the documentation. Check I can the set values on the Thursday, then am local.
However, I forgot to mention that the last reason of the protection tripping U > was.

Would the vector jump relay not only in RUS-side short interruptions come to fruition? The public mains network seems to be stable?

And also my question? I don't know that the EVU there has influence.

Gas igniter

so I thought, I build me an testing jobs  elektrozünder just figured, I build spark gaps, which I can easily press with a 10-meter line from the distant me ne. to do this I need but a device / a circuit etc, with which I can generate the necessary voltage out power. how so, how do I build something best, easiest and most affordable?
Thank you times ahead...

E shocker with quadruple cascade, transformer and components of Pollin, costs around €6 plus shipping.
Disadvantage: a 5mm spark ignites only around 1-3mal per second.
Tesla Kit Oppermann (transformer blocking oscillator with power transistors), ca €12 plus shipping.
Disadvantage: 12V battery, or similar required.
Power is but required at all.

To the light of gas mixtures the spark of a small cascade should be sufficient but.
