Estudio de carga eléctrica para la repotenciación del circuito eléctrico en baja tensión del transformador existente número 1 de la empresa Sucesores de J Paredes M S.A.

Abstract

The main objective of this study is to detect possible anomalies that may contribute to the resizing of the low voltage section connected to transformer #1, which belongs to the company Sucesores J. Paredes. The inspection begins with a review of the electrical infrastructure, which required field visits, quantification of power quality magnitudes and thermographic checks. It is essential to describe the current state of the company's electrical system, in order to verify compliance with existing standards such as ARCONEL, which relate to power quality parameters. Consequently, the low voltage circuit of transformer #1 was subjected to a thermographic study based on the requirements of the ANSI/NETA ATS-2009 standard, to identify potential deficiencies, such as electrical leaks, loose connections and overloads. The analysis indicates that there are 11 protections working with overloads. On the other hand, the power quality assessment revealed that the power factor, frequency and voltage THD parameters comply with the requirements of the standard. However, the current THD exceeds the allowed range. Also, voltage anomalies are another problem and are related to a weak power supply.
