Complete design with load analysis of a 500kV electrical substation with breaker-and-a-half configuration. This substation had 6 overhead lines and 6 single-phase transformer, it was designed according to local regulations and international standards. Design of a distribution system for Alcala substation in Bogotá (2013) National University of Colombia – Transmission & Distribution Systems. A design of distribution system for the area located between Calle 127 and 134 and Carrera 19 y 54 of Bogota. Firstly, data gathering of the area has been made, identifying load types and consumption with 20 years of projection. According to this, each transformer and public illumination were located. Besides, conductor has been specified and regulation, losses and economic analysis of this Project was made. Another developed projects: • Design of a wireless EV Charging Station. National University of • Design of a 214 km overhead line in Colombia. National University of • Design of a High efficiency and low-cost LED Bulb with 300 luxes of illuminance.

Bonding systems were designed and short circuit analysis were performed. Mechanical design of structures for outdoor terminations. 3 HV Prysmian, 3 NKT joints and 6 Non Self-Supporting Termination were installed. 1,4 km of 123 kV NKT Subsea and 1 km of underground cable were laid. • Electricaribe – El Bosque Substation – Cartagena 80 ESF-115kV terminations, 3 ESS245 245kV and 36 CONNEX 115 kV were installed. 4200 m of 115 kV insulated cable and 200 m of 230 kV insulated cable were laid. • EPM – Substation of José María Córdoba Airport – Medellín 8 115kV ESP-115 terminations were mounted. • Electrohuila – Subestación El bote – Palermo Retrofitting of MV substation. • Telmex – Electrical Works– Soledad Increased loading capacity to 1000kVA at 13200 V for datacenter facility. • Telmex – CCM Venecia – Bogotá Increased loading capacity to 2250 kVA at 13200 V for datacenter facility. Ingeniería y Proyectos de Colombia - (February 2015 – August 2015) For improving the quality management systems of the company, a study of procedures for pre-operational tests of protection systems for high voltage substations, overcurrent, and distance relays, as well as main configurations of high voltage substations are made. These procedures include a review about the theory of protection systems functions, their main characteristics, and a brief explanation about overcurrent and distance relays is given. After that, a case study realized during the internship is described, and the main parameters of the SEL 421 and SEL 451 relays (previously characterized through the reference manual of manufacturer) are explained. In addition to this, general security procedures and tests in-situ for guaranteeing reliability, robustness, and selectivity of the distance and overcurrent protections for a specific substation were made. Corporación para la Energía y el Medio Ambiente - (February 2013 – February 2015) Energy Characterization and identification of solutions to improve efficiency in electric machines for industrial and residential sector, Thermographic analysis and electric installations evaluation according to international and local regulations. Illumination verification to different sectors according to local and international regulations.
