ICT supported laboratory testing of installation circuit breaker

Circuit breakers are one of the most common safety devices in electrical circuits. Presentation of their characteristics to the students will be shown in this article. Characteristics could be shown in three different ways. First way as convenient experiment with standard instruments and mutual presentation of achieved results. Second, as building model in mathematical modeling software and critical review of corresponding results. And third as fully automated experiment with programmable logic controller for control and data acquisition and visualization software for automated results presentation. All three ways of presentation of these characteristics to the students will be critically reviewed.
