Projeto de Banco de Capacitores para Correção de Reativos

A significant portion of energy consumption in user units stems from inductive loads, including motors, transformers, lamp ballasts, and induction furnaces. These inductive loads rely on a magnetic field to operate, necessitating the utilization of both active and reactive power.

Power Factor Correction through capacitor installation has become a crucial focus for design, maintenance, and financial teams aiming to optimize electrical equipment consumption. To improve the utilization of generated electricity, the former DNAEE (National Department of Water and Electric Energy), now known as ANEEL (National Electric Energy Agency), mandated, via Decree No. 479 of March 20, 1992, a minimum power factor of 0.92.

This course aims to equip students with the knowledge and skills to understand the concepts, techniques, and regulatory requirements of power factor correction for reactive power compensation in electrical installations. By addressing excessive reactive power, you can avoid penalties associated with excess reactive power charges on energy bills and achieve greater energy efficiency, leading to substantial cost savings for consumers.

Common Causes of Low Power Factor:

• Inductive Loads: Equipment like motors and transformers inherently contribute to a lower power factor.
• Low-Load Transformers and Motors: Transformers and motors operating at reduced capacity exhibit a lower power factor.
• Excessive Capacitive Loads: An imbalance with too many capacitive loads can also negatively impact the power factor.
