| Sumario: | The little accessibility to a tool that allows knowing the behavior of the insulators under conditions of extreme humidity and contamination, motivated our effort to develop a mathematical model in MATLAB that makes possible the analysis of dielectric breakdown in porcelain, polymer and glass insulators at 13.8 kV. Obtaining the The model was based on bibliographic research, and the subsequent representation of the circuits of the tests, the Hipot Huzheng of 50 kV and 5 kVA was used. Based on these representations and the known physical laws, the equations were obtained and formed the differential systems that led us to conclude on obtaining the mathematical model. Once the mathematical model was structured, it was integrated into the graphical user interface of MATLAB or GUI, through an application that includes the options to simulate different environmental and pollution conditions such as: temperature, humidity, electrical resistance, atmospheric pressure, applied voltage level and electrical arc length. The model allows us to observe how the insulators act if they are exposed to industrial frequency pulses, determine the leakage current and the possible dielectric breakdown based on the factors already indicated, but also reveals the way in which the insulators used in distribution networks handle lightning impulses; finally, the application developed it also outputs the voltage at which dielectric breakdown occurs. In the validation process, the mathematical model proved to have a good level of accuracy. |
