Análisis y diagnóstico del sistema de puesta a tierra de la S/E 03 Monay

Abstract

The importance of the System of Grounding in an Electric Substation, is essential for the S/E to continue with the correctly operation. In the event of a fault, the grounding system must be designed to withstand the ground fault current and provide safety for people and equipment. The touch and step voltages must not be greater than the permissible voltages for people with a weight of 70 kg, the evaluation of the system of earthing of the S / E 03 Monay was made by using the IEEE Std - 2013. The grounding system that is currently in operation is compromised by the deterioration of the materials and the increase of the short-circuit current. In this work, a study is made and then a resizing so that the current grounding system returns to comply with the safety conditions and that it performs its correct functioning in the event of a possible failure. Finally, the Centro Sur Electric Company may review the designs for future S/E or S/E that are in operation through the program for the correct design of grounding systems in S/E AC using the IEEE Std 80 - 2013.
