Below the Curie temperature, spontaneous polarization prevails between the individual grains of the PTC material. The negative grain boundary charge is thereby shielded. This reduces the potential barriers between the grains at low temperatures below the Curie temperature. Above the Curie temperatures, the dielectric constant is much lower than below. Above there is no ferroelectric order and no spontaneous polarization. The shielding of the space charge zones will be much more ineffective and the Potentialbarierren increase. As a result, the resistance in the transition from low to high temperatures increases by three to six orders of magnitude.

  • the PTC thermistor 17 thus assumes a larger part of the current with increasing load of the spark gap, whereby the load within the spark gap itself is reduced and also the extension of the arc by reducing the pressure and the current forces can be limited.
  • a majority of the arc current is taken over by the PTC thermistor, causing it to heat up and automatically increase its resistance.
