Abstract
The results of the commercial indictor gas tube inv estigation, by the time delay measuring method are presented in this paper. This tube is usually used as a indicator of many electrical appliances. The experimentally obtained time delay distributions fo r different voltages (80 V, 90 V and 100 V) and different relaxation times (from 1 ms to 20 ms) are presented. It is shown that time delay distributio ns have Gaussian shape, and that used gas discharge tu be has very small memory effect. Small memory effect indicates fast response, and consequently go od characteristic for indicator tube.

Summary
Investigation of electrical breakdown in gases is important for describing processes and characteristics of gases as well as their practical applications [1]. The electrical breakdown time delay method for DC voltages, used in this experiment, gives very useful information about electrical breakdown, cathode effects, concentration of ions, electrons and neutral active particles in the afterglow [2], [3]. Mentioned method gives many useful informations about reliable of commercial gas components [4], [5], which are very significant in practical applications. The statistical theory of the electrical breakdown is described on the base of Townsend breakdown mechanism [6]. Breakdown criterion, according to Townsend theory (for small pressure and small overvoltages, when the influence of the space charge is neglected) is: γ exp d
