    The objective of this research was to evaluate the power quality at the Points of Common Coupling (PCCs) of the low-voltage network of the main plant of INDUACERO Cía. Ltda., through the measurement and analysis of the main electrical parameters established by the applicable technical standards. To achieve this, information on the electrical system was collected, the installed loads were characterized, and a seven-day continuous monitoring period was conducted at the main switchboards associated with the 75 kVA and 45 kVA transformers using a Fluke 435-II power quality analyzer. Additionally, a computational model was developed in ETAP to complement the analysis of the operating conditions observed in the field. The evaluation included parameters such as voltage level, voltage and current unbalance, harmonic distortion, power factor, flicker, and grounding system condition. The results showed that voltage levels, harmonic distortion, power factor, and flicker complied with the limits established by the applicable regulations. However, elevated neutral-to-ground voltage levels were identified at both PCCs, inadequate performance of the existing grounding system, significant current unbalance at PCC-A, and recurrent transformer overload conditions at PCC-B. Based on the findings obtained, technical solutions were proposed focusing on the redesign of the grounding system and the redistribution of loads to reduce the overloading of the 45 kVA transformer. The results provide a technical basis for decision-making aimed at improving the operating conditions, electrical safety, and reliability of the plant's electrical system
