In this paper we will propose the procedure adopted to build a didactic device, which aims to demonstrate the operation of a didactic electrical protection system (DEPS). The protection system operates through the activation of the equivalent circuit of a digital relay, which uses voltage and current sensors to enable protection through defined settings, that will trigger the relay to deactivate the charge whenever the sensors detect an unexpected operation situation. The protection system uses an ATmega328, because it is a simple microcontroller, didactic and easy to program. The DEPS was built with basic electronic components, that can be easily acquired, which facilitates the replication of the project, allowing the student to get familiar with the concepts of electrical protection system that are addressed in more advanced courses, as soon as he begins his studies in electronics.

Key words - Teaching equipment, Electrical Protection, Digital Relay.
