Construcción de módulo didáctico de protección diferencial de transformadores para el Laboratorio de Protecciones Eléctricas de la Universidad Politécnica Salesiana Campus Sur

Abstract

Research and improve in the practical part, is forced to use physical equipment that allows his development, so a laboratory must continually meet the technical needs with methods in which allowed to implement or develop modules that can be improved or easily updated. The presented project will complement the electrical protection laboratory allowing the student's study and research to be facilitated, through the implementation of a physical module developed together with LabVIEW, which simulates an electrical protection based on the operating principle of a differential protection for transformers. The module can be controlled by means of a graphical interface, allows to show the connection group of its windings together with the angular displacement, and is capable of acting as a differential protection in case of a fault. This document shows an analysis of the characteristics of the transformers depending on the type of connection used, technical information about transformers, differential protections for transformers, as well as configurations, connections, design drawings, among others, and its can be used to help and give support the use of the module. In the second chapter general technical information is described in an introductory way to know aspects that are used in the construction of the module. In the third chapter, detailed information on the physical and technical design is presented, as well as information on the construction of the module. A comparative and quantitative experimental research methodology has been used for the development of the project.
