Estudio para la optimización del dimensionamiento de transformadores de distribución utilizados en edificios del centro norte del Distrito Metropolitano de Quito

Abstract

At present, the Quito Electric Company faces a problem of underutilization of the distribution transformers that are located in the chambers of the buildings destined to departments and commercial premises; resulting in economic and energy losses due to the fact that the installed capacity of these transformers is not used efficiently. The factors of use to be indicators of use of distribution transformers; they are calculated using the maximum demand and power of the installed transformer. These factors are found in low percentages due to the consideration that is made in the procedure currently used for the dimensioning of the capacity of the transformer to be used in the chamber; procedure found in the regulations in force at Empresa Eléctrica Quito; taking as a basis: simultaneity factors, nominal power of equipment, luminaire power, among others to determine the design demand to be considered in the transformer. Demand values that can currently be improved due to the technology that directs energy savings (energy efficiency). In addition to this, other sizing criteria for distribution transformers will also be analyzed, according to the existing situation in the Metropolitan District of Quito, proposing an adjustment to the existing regulations of the Quito Electric Company.
