In the past, simple protection systems of electric motors based on components such as timers, contactors, electromagnetic switches, and voltage and current transformers were slow and inaccurate, as well as low sensitivity. However, the production of PLCs and their application in this field eliminated the mentioned problems. Extensive operation of motors, being the main executive equipment in the field of application, requires the creation of modern automated protection systems to ensure their reliable and stable operation. Today, PLCs are continuously evolving and striving to be the best choice for various industrial automation applications. Since the PLC-based protection system is a reliable, fast, high-precision system, modern protection systems based on PLC of electric motors are researched in the article.
