Implementación de un sistema interfaz hmi para la adquisición de datos en pruebas de transformadores.

Abstract

Inside the transformer´s laboratory in the UPS-Guayaquil the class of Electrical Machines is dictated, which includes the study of the Transformers analyzing their behavior and operation, this analysis needs data for their respective representation with different graphs that indicate their behavior. The necessary data are obtained by sampling at the time of performing the practice, these data are acquired manually using a digital meter, this can be a multimeter or ammeter. With these data we make tables to process them later and obtain the different graphs that demonstrate the operation and behavior of the transformer. This data collection, by performing it manually is prone to errors, in addition the accuracy of the practice would depend on the number of samples obtained, in this work it takes a considerable amount of time. This is how the idea of implementing an HMI interface for the acquisition of this data arose and that they are processed and displayed by a software, in this way we will verify that the theoretical data and measured manually, are the same as the programmed software, in addition to giving us a report on the status of the transformer under test. This tool allows us to give a professional criterion about the status of a distribution transformer, because this element is the most important in a network.
