This work relates to theHigh voltage study of the effect of pollutionPollution on the insulatorsInsulator of high-voltage overhead power lines. The study will be carried out using a new laboratory model for flashoverFlashover studies. This model resembles a real outdoor insulatorInsulator with respect to its shape and pollutionPollution. We carried out a series of experiments to measure the resistance of pollutionPollution between the electrode of mass and a static dischargeDischarge in various positions of the dischargeDischarge on the surface of the electrolyte as well as the current and critical voltage. The experimental results of this model and their analysis were performed in two groups: The first is the measure of pollutionPollution resistance between the ground electrode and a static dischargeDischarge for many dischargeDischarge positions. The second is the measure of critical current and critical voltage according to the position of the dischargeDischarge starting point. A comparison with the case of a point-to-point gap reveals that the electric field in the air in the vicinity of the electrolyte surface is responsible for the dischargeDischarge elongation, and the critical conditions of flashoverFlashover are the weakest initial electric conditions necessary to create this field distribution. The results obtained verify and agree with those of other research works referring to devices considered as prototypes of work and allowing to validation of this model.
