EMP generator! I got something completely different from what I came to life .
Interesting fact: the coil is a kind of shortened helical antenna and, as a result, emits electromagnetic waves. It emits very badly. A significant part of the electromagnetic energy is reflected and returned back to the generator, which leads to extremely negative consequences. And if you do not take special measures, then the high-voltage power supply will not last long ...
That the coil emits, I realized right away when, when the spark gap was triggered, the LED lamps in the room blinked for a short time. At first, I decided that RF currents enter the mains bypassing the noise suppression filters of the high-voltage power supply. Subsequent detailed inspection did not confirm my guesses. Interference actually penetrates the power grid, but noise suppression filters have nothing to do with it. HF currents have worked their way into the power grid through the conductive connection of the coil to the wiring. This state of affairs came as a complete surprise to me. The risk zone includes: electronic devices connected to the power grid, Ethernet network and the nerves of neighbors. It is hard to imagine what a person would think of if a table lamp with an energy-saving lamp flickering in the dark, the power cord of which is not connected to the outlet ...
