Rediseño del sistema eléctrico en baja tensión para la Universidad Politécnica Salesiana Campus El Girón bloque b basado en una campaña de medidas para la ejecución de un plan de mejoras

Abstract

This research analyzes the low-voltage electrical system of Block B of the Universidad Politécnica Salesiana Campus el Girón, thanks to the help of an electrical measures campaign and the survey of existing electrical plans. First, a taking measurement is done to verify the quality of electrical energy in relation to the CONELEC 004/01 Regulation. Second, earthing systems in data center, generators and main switchboards are analyzed; then, the resistance is determined and it is compared with the IEEE 142-2007 standard. Third, the capture of the temperature differences of the elements placed on the boards and sub-boards is done; these data are compared with the NETA / ANSI ATS-2009 standard in order to establish the degree of relevance. Furthermore, the phase sequence in the ATS supplied by the Empresa Eléctrica Quito is analyzed using the Pro’skit 8PK-ST850 instrument. Finally, power measurements are made in order to determine the percentage of use with respect to the 150 KVA transformers installed in Block B of the University. Regarding the energy quality analysis, all the elements comply with the standard, that means, that the voltage does not exceed ± 10% of the quality index, the power factor is equal to or greater than 0.92 and that THDs do not exceed 5 and 6% in the third, fifth and seventh harmonic. A grounding design is carried out on the generator 1, so that its resistance is less than 5 ohms. Then, it is proposed to perform cleaning maintenance on the main breaker of the biotechnology laboratory and the analysis for better load distribution on the STP-SP-B-1 sub-board. Finally, it is proposed to do the same load analysis on the main distribution panel TDP-PB-B-1 of the South Zone.
