An Educational Didactic Machine to Improve the Learning Process of Motor Protection Mechanisms in Electrical Engineering High Education

In recent years, educators and engineering students have become increasingly concerned with classroom teaching and learning, especially the challenges of improving teaching that are so important to the education of Engineers. One of the biggest challenges is getting students to try and experience hands-on activities quickly and easily understanding. Many universities rely on adequate infrastructure, laboratory availability, and minimum budget to make students experience this experience in practice. For Electrical Engineering students, these challenges are even greater when the use of practical and well-equipped laboratories is required, especially in activities with power systems and electric motors. This paper presents the development and design of a Didactic Workbench for Motor Protection (DWMP) that allows students to simulate different types of three-phase motor failures. In addition to simulating failures, the workbench performs different protection actions of these motors through an Intelligent Electronic Device (IED). Thus, it is expected to assist the student in the learning process to identify, interpret and act on faults and protection of electric motors.
