Taking into account the socioeconomic stratum of consumers of electricity. The analysis of the behavior of the demand, allows to establish the curves of daily demand and the behavior of the power factor by socioeconomic stratum and for working and non-working days. It is considered that this evidence is an input to establish the maximum demand diversified curves, indispensable for a correct sizing of transformers and even of low voltage electrical gridsÍtem Caracterización por estilos cognitivos y de aprendizaje de los estudiantes de Tecnología en Electricidad de la Universidad DistritalPérez Santos, Alexandra Sashenka; Molina Vásquez, RuthThe work presented in this thesis aims to the characterization of cognitive styles, learning styles and learning strategies of the students of Technology in electricity at the Technological Faculty of the Distrital University. The characterization was performed according to the Curry’s onion model (Lopez, 2012) repeatedly employed in previous studies where cognitive styles and learning styles were separately analyzed in populations of primary and secondary school education. The present study contributes two fundamental aspects, the simultaneous characterization in the three constructs and the analysis of population of undergraduate education, particularly at the Engineering field where the characterization of learning styles and strategies is even more scarce.Ítem Desarrollo de una herramienta ofimática de mejoramiento en el análisis de calidad de la energía eléctrica para la empresa Proyelect Ingeniería sasRamos Vargas, Giovanny Andres; Pérez Santos, Alexandra Sashenka; González Pedraza, Camilo Andrés; Pérez Santos, Alexandra Sashenka [0000-0003-3286-5861]; Gonzalez, Camilo Andrés [0000-0002-6705-7920]The company proyelect engineering sas has identified a problem that affects the proper conduct of operations with electrical energy quality analysis equipment. The above is generally evidenced by the errors associated from the installation stage of equipment that parameterizes the customers' energy quality data, difficulty in interpreting the data provided by the quality equipment, these being required by the Colombian technical standard for power quality in common node (Ntc 5001). Due to the above and meeting the needs of current clients, mainly in the hospital field, the intention arises at proyelect engineering sas, to implement guidelines that allow us to cover matters related to the Quality of Electrical Energy, thus safeguarding the proactivity of the company. By looking for tools and improvement of processes that are currently not fully defined, with this, we also seek to create opportunities for improvement, which can be evidenced in the development of this internship.Ítem Diagnostico, Levantamiento y Consultóría de los Equipos de Subestación Eléctrica y Redes Principales hasta Tableros Generales Del Hotel Santa Clara Cartagena.Gonzalez Castro, Daniel Camilo; Herrera Cubillos, Andres Felipe; Pérez Santos, Alexandra SashenkaCurrently the Hotel Santa Clara has an installed load of 1600kVA, which is supplied by the local network operator ELECTRIFICADORA DEL CARIBE S.A. E.S.P. The hotel is fed through a medium voltage network that enters the premises underground at a voltage level of 13.2kV (circuit CHAMBACU 7). It passes through a configuration of medium-voltage cells isolated in air from which the Hotel Santa Clara and three other buildings adjacent to the hotel are fed, that is to say that the hotel houses in its facilities areas of easement in which equipment is found that are owned by ELECTRIFICADORA DEL CARIBE SA E.S.P ... Once the stage of the medium voltage cells has been passed, the electrical transformers of the project are fed through protection cells with HH fuses isolated in air, the project currently has three transformers, one of 800kVA; 13.2kV / 440V and two 400kVA transformers; 13.2kV / 208V (See Annex 1), from which the power supply of each of the project's electrical loads is derived. In addition to the above, it has two power plants which provide partial replacement to the Hotel Santa Clara. As noted in the previous description, it is evident how robust the hotel's electrical infrastructure is, this added to the importance of the hotel, make sure that the electrical network is safe, and reliable, and also have the spaces suitable according to the electrical requirements. For the above and starting from the point that the hotel facilities have been in operation for more than 20 years without having undergone any remodeling (Annex 3.), it is necessary to perform some consulting work which will allow to determine the state of the equipment of the electrical substation and the main electrical networks to general boards in order to determine in what conditions the hotel is currently operating under Colombian regulations. In addition to the above, it must be taken into account that it is clear that equipment and electrical networks complied with their useful visa cycle. This, together with the obsolescence of the technologies used in 1995, means that the electrical substation and the main electrical infrastructure of the hotel do not be according to the needs of the sameÍtem Estrategia de Enseñanza y Aprendizaje ABP Aplicada a Circuitos II- Circuitos TrifásicosHincapié Alvarez, Maryid Paola; Usaquen Usaquen, Jorge Armando; Pérez Santos, Alexandra SashenkaDesign and development of virtual classroom of chapter 3 three-phase circuits of the subject circuits 2, which in turn is articulated to the virtual classroom of electrical measurements. The virtual classroom is focused on learning based on problems, that is, on situated learning, the virtual classroom has theoretical development of the programmatic content of said chapter, exercises located each of the content themes supported with their corresponding simulation, additionally has an evaluation line that allows to identify the process and the level of learning in which the student is.Ítem Estrategia de Enseñanza y Aprendizaje ABP Aplicada a Circuitos III-Circuitos de Orden UnoRojas Zarazo, Diego Armando; Páez Parra, Yuli Tatiana; Pérez Santos, Alexandra SashenkaThe traditional resources for the teaching and learning of circuits III and the academic achievement that has been obtained, demands the proposal of strategies, that support and reinforce academic activities student-teacher inside and outside the classroom, in order to linking theoretical content with practice in a real context. An innovative way of implementing the above can be achieved through the use of Information and Communication Technologies (ICT), establishing a virtual environment for the teaching and learning of circuits III. The initiative of an alternative teaching and learning strategy will be implemented with the development of Chapter 1: "One-order circuits" of the programmatic content of Circuits III version 1 prepared in 2015, based on the BPA.Ítem Estrategia de Enseñanza y Aprendizaje ABP Aplicada a Medición de Corriente Directa en Medidas Eléctricas: Clase 2 a la 4Ovalle Murcia, Gerson David; Pérez Santos, Alexandra SashenkaProvide situations and explanations using meaningful learning and located where the student feels identified and can apply them to their learning and work; in order to strengthen the knowledge acquired to be the basis of future teachings.Ítem Estudio comparativo técnico-económico de la alimentación para las cargas eléctricas de las 24 pilonas y el alumbrado exterior aferente a las estaciones del sistema de cable aéreo para la localidad de Ciudad Bolívar por medio de redes de distribución o paneles fotovoltaicosSánchez Orjuela, Luis Alberto; Piraján Rodríguez, Mauricio; Pérez Santos, Alexandra Sashenka; Pérez Santos, Alexandra Sashenka [0000-0003-3286-5861]This work of degree present a comparative technical-economic study of the electrical connection for the electric charges of the 24 support structures and the external lighting around to the stations of the aerial cable system for the district of Ciudad Bolívar through distribution networks or photovoltaic panels.
