high-voltage emissions

During this experiment, various values of high voltage capacitors were tried to lower the radiated emission value much below the limit line to have enough margin. The final values of the capacitors 22pF, 0.01uF are shown below in the circuit (mistake in diagram, should show 22pF).

  • X-RAY EMISSIONS IN VACUUM RELAYS | Gigavac

    Above 15 kV, all products that operate in a vacuum, including vacuum relays, can produce X-rays that can be considered hazardous. This is one reasons we recommend using GIGAVACs SF6 gas filled relays because the electrons collide with the gas molecules and are unable to accumulate sufficient energy to make significant radiation.

  • HIGH VOLTAGE PROCESSING OF VACUUM RELAYS | Gigavac

    Vacuum is an excellent dielectric. However, sometimes a vacuum relay may show reduced dielectric strength over a period of time. This is generally caused by a trace amount of free ions out-gassing from the metal or ceramic materials inside the relay. Normally, this is not noticeable because when the rated high voltage is applied, the free ions become charged and deposit themselves on the
