  • the protective device 1 is based on the technology of air gaps.
  • the protective device 1 according to the invention uses encapsulated spark gap technology, the air then being replaced by a gas, for example a rare gas maintained under controlled pressure.
  • Such spark gaps undergo, during their lifetime, degradation. This degradation can be gradual or abrupt, especially the spark gap is used intensively or repeatedly, with a high frequency. Several phenomena, specific to the gaps, can lead to this degradation of the protective device.

These metal particles are then likely to be deposited at another place in the inter-electrode space, thus creating a conductive pollution within the spark gap. This pollution can lead, when important, to a failure of the spark gap, several evolutions then being possible until the end of life of the spark gap.

  • isolation distance here refers to the distance that the electric arc must travel to electrically connect the electrodes 2, 3. It exists, when the spark gap is operational, that is to say non-degraded , a so-called “functional " isolation distance, which corresponds substantially to the width of the inter-electrode gap 4 necessary for an electric arc to start when an overvoltage reaching or exceeding a predetermined threshold value occurs.
