Evaluación de medidas de prevención y control del riesgo eléctrico para las redes soterradas de la ciudad de Ambato.

Abstract

The objective of the work, Evaluation of Electrical Risk Prevention and Control Measures for the Underground Networks of the City of Ambato, was to identify the electrical risk factors in the underground networks of the Empresa Eléctrica Ambato Regional Centro Norte S.A. and evaluate the level of risk in the present conditions, using as a basis the methodology contained in the General Annex of the Technical Regulation of Electrical Installations (RETIE) of the Ministry of Energy and Mines of Colombia. Then, prevention and control measures were proposed to eliminate or minimize the risks found, taking into account the hierarchical order, source, medium and receiver, according to the ISO 45001 standard. The effectiveness of the proposed measures was evaluated through the use of the event trees methodology and it was found that the measures significantly reduced the electrical risk. These include the use of protection barriers, ground fault protection systems, improvement of insulation and changes in work procedures, training and training on the correct use of personal protection equipment and techniques to detect and control step voltages.
