Definitions

  • a small opening 23 is provided in the peripheral wall of the spacer member 13 at a locality situated opposite the excentric projection 20 and hence opposite the locality 21 of initial response, the opening 23 occupying substantially the same diametrical plane or range as the initial arcing locality 21.
  • the opening 23 is formed by a recess in the spacer member 13 extending over the entire cross-section of the ring inner portion 16.
  • the width of the opening 23 in the peripheral direction of the spacer member is approximately as large as the diameter of the projection 20. Consequently, the opening 23 is approximately 2 to 5 times as large as the length of the breakthrough gap at the initial arcing locality 21, the drawing, for lucidity, being not true in this respect to actual measure.
