Development of a Rain Simulator for a HV Laboratory

Tests in rainy conditions are mostly used to determine the behavior of the dielectric elements against moisture. This project presents the development and construction of a sprinkler type rain chamber, which was designed according to the needs and dimensions of the high voltage laboratory of the “Universidad Politécnica Salesiana Sede Cuenca”. The guidelines established by the IEEE Std. 4-2013 are followed for both flow rates, pressures and water treatment to achieve the resistivity value of the normalized liquid for the different tests. The camera is built with fiberglass and tempered glass, with the respective hydraulic circuits to produce the precipitation. The project is complemented with a table of simulator prices and a behavior test of a pin type insulator in dry and wet conditions.
