This paper presents the results of our investigations of breakdown mechanisms, as well as a description of their influence on the distributions of time delay distributions, for a gas tube filled with nitrogen at 4 mbar. The values of the time delay are measured for different voltages, and the values of the relaxation times and their distributions and probability plots are analyzed. The obtained density distributions have Gaussian distributions and exponential distributions for different values of relaxation times (Gaussian for small values and exponential for large values of relaxation time). It is shown that for middle values of relaxation time the delay distributions have a shape between Gaussian and exponential distributions, which is a result of the different influences of electrical breakdown.

“…The main deficiency of GDTs in terms of protective effects is their considerable discharge delay and unsatisfactory response sensitivity, which makes it difficult to cope with large lightning surges of wave head rising steepness. There is a follow-current problem in the lightning protection of the power supply system [16][17][18]. According to IEC61643-311, if a supply GDT creates power-frequency follow currents, it is advised that it is extinguished at the 30-phase angle once the first power-frequency current passes zero and that there be no breakdown [19][20][21].…”

A short-circuit fault in the gas discharge tube (GDT) is one of the latent hazards of electrical equipment. It may cause the ignition of electrical equipment. Therefore, based on the existing GDT, an improved external open-circuit failure gas discharge tube (EOFGDT) which can remove short-circuit (SC) failure is presented in this paper, and its structure and working mechanisms are introduced. This EOFGDT can utilize the combustion and heat transfer of continuous arcs due to SC failures to increase the temperature of its end electrode, so as to induce a solder joint failure, by which the elastic sheet on the solder joint becomes disconnected from the end electrode, forming an external gap that reduces the rising speed and amplitude of the recovery voltage across the arc gap, and eventually forms an open circuit (OC) within the structure. The EOFGDT SC condition was simulated and a test of the EOFGDT ability to remove SC faults by using an 8/20 µs impulse current generator coupled with a power-frequency power supply test bed was conducted. The experimental results show that the magnitude of the SC follow currents, power-frequency voltages, and the impulse currents are positively correlated to the OC response time, which is greatly affected by the power-frequency follow currents. When the SC current reaches 30 A, the EOFGDT OC response time is about 350 ms. The experimental waveform is consistent with the screen result of the OC response time of the EOFGDT, which proves the effectiveness of EOFGDTs for the inhibition of SC follow-current failures.

“…Neon is used in many of electrical component, pure or in mixture with some other gas. For example, it is used in neon glow lamps, in indicators glow tube [13], in starters [14], in sodium-vapor lamp, and in gas arresters [15]. Beside of that, recently neon has applications in plasma panels, in mixture with a small percentage of Xe or Ar [16].…”

The results of investigations of electrical breakdown mechanisms, and their influences on the time delay distributions are presented. The investigations are performed by analyzing the density distributions and probability plots of experimentally obtained time delay distributions for different relaxation times and overvoltages in gas tube filled with neon at 10 3 Pa (10 mbar). The time delay density distributions are fitted with Gaussian distributions for relaxation time smaller than 15 ms and exponential distributions for relaxation time greater than 150 ms, while in the region of relaxation time between 15ms and 150 ms with the Weibull distribution.
