This article focuses on defining the reference state of industrial machines by analyzing key electrical signals such as voltage, current, and power. The goal of defining the reference state of machine functionality is to compare the real-time state of machines with the reference state, enabling improvements in their performance, efficiency, energy consumption, and ensuring more reliable operations. This approach involves gathering historical electrical data from machines and operational logs and analyzing them to generate clear and precise insights into machine performance and reference functioning across various modes of operation. Real-world applications of comparing the actual state of the machine with the reference states can make maintenance more efficient, improve data-driven maintenance decisions, reduce downtimes, and enhance reliability. This article highlights the potential and possibilities of using electrical data to achieve more efficient and reliable operations.
