Valoración, diseño y asignación del sistema de puesta a tierra para las torres de las líneas de transmisión del proyecto refuerzo suroccidental a 500kV, con el fin de cumplir con las tensiones de paso y de contacto

Abstract

With the purpose of complying with the provisions of the RETIE "Reglamento técnico de instalaciones eléctricas" (Technical regulation of electrical installations), regarding the step and contact voltages that may occur on its lines, Grupo Energía Bogotá (GEB) sought during this internship to review and assign the grounding systems for the “Refuerzo Suroccidental” project consisting of sections 1,2,3 and JUPA connection, dividing the project mainly into two parts; A first part consisted of evaluating and reassigning the grounding systems of sections 1,3 and JUPA connection, which are already under construction and required rapid treatment to comply with the step and contact voltages as established by the RETIE , and secondly, carry out a more detailed study of the ground fault currents using the ATP software to be able to assign the grounding systems for section 2 which is in the licensing process and has more time to assess different options.
