Comissionamento da malha de aterramento da subestação Cacimbas 34,5/230 kV do complexo eólico Bons Ventos da Serra 2

Abstract

The Brazilian electrical system is constantly expanding, which results in the need to develop the entire national interconnected system, which implies the construction of power plants, transmission lines and energy substations. Seen, the systems are compatible with the proper form, maintaining their due continuity, aligning their stable performance to personal safety. To this end, it is extremely important that the electrical landfill of the installations is properly designed and mainly commissioned correctly. Under these conditions, the need for special care in all tests carried out without commissioning is evident in energy substations. The environmental and environmental issues included are essential for the project to be carried out and delivered in an integral, safe and efficient manner. established in national and international standards of concern to the topic. The present work presents a description and analysis of the tests performed without commissioning of the landing strip of the Cacimbas 34,5 / 230 kV collector substation, gathering real data and exposing as main characteristics of the tests carried out, following the recommendations of the standards: ABNT NBR 15749, NBR 15751, IEEE std 80 and std 81. The paper proposes a theoretical and practical basis for conducting the commissioning tests of a grounding system in a substation, becoming a reference for engineers and technicians who in the area.
