Diseño de un banco de pruebas de protecciones eléctricas

Abstract

The objective of this project is to design some schematics that can produce all electric failures that could be found in an electrical installation. The purpose of this is helping university students to learn how this electrical protection works. Firstly, knowing that the main users of this project are university students instead of qualified professionals, the project has to be designed to be safe for the user. In this case, the user will manipulate a low voltage circuit. This low voltage circuit will close the “high” voltage circuit producing the electric failure. Furthermore, all the circuits must have a low level of consumption. This low level of consumption allows the use of cheap components in the project reducing the total price and the cost of the used energy. The project must have at least five types of electric failures. These failures are a short-circuit, a ground contact, an over intensity and an over permanent and transitory voltage. Like mentioned before, these schematics have to be safe for the user and don’t spend a lot of energy. To conclude, we have to calculate the value of some components and later simulate this circuits using a program and checking the correct function of the schematics. The program that is going to be used is “ORCAD Capture”.
