Optimización energética de los transformadores de la Escuela Superior Politécnica de Chimborazo y delimitación de sus centros de carga

Abstract

The energy analysis of two transformers of Mechanics Faculty belonging to the buildings of the Laboratory-Dean's Office and the classroom building of the Industrial Maintenance Career was carried out to determine the actual capacity of the transformers based on electricity consumption and analyze the quality of energy that is supplied by the electrical network, examining possible electrical anomalies while the buildings are at their maximum electrical consumption load. The Fluke analyzer was connected for an estimated seven working days, and the information was stored every fifteen minutes. Through the Power-log software's assistance, the equipment's historical data was downloaded for its subsequent analysis through regulations and resolutions of the Ministry of Energy and Non-Renewable Natural Resources to determine the efficiency of the distribution transformers. They also helped to determine the optimal consumption capacity of each building. Once the data from the two buildings were collected, the calculations were made, and through the interpretation of the Fluke analyzer graphs, the real power consumption of each building was known. It was determined that the readings reached a voltage of 130.09 V; however, the recommended calculations voltage that must be supplied to the Industrial Maintenance Career building is 127V. The power of the transformer installed in the Maintenance building is 50kVA, through calculations it was determined that the actual consumption power is 21.55 kVA, being oversized by 28.45kVA, while the power of the transformer in the Laboratory-deanery building is in a tolerable range. Therefore, it is recommended the appropriate personal protective equipment be used for the next data collection to connect the analyzer.
