Electrical engineering students need to understand and visualize the operation of high-voltage installations comprehensively. However, laboratory-related equipment for these kind of subjects results expensive (even unaffordable in some cases) and very dangerous, thus requiring well-equipped installations, while on-site visits result equally dangerous and system operators are typically reluctant to allow these activities in their own installations. In this regard, faculty staff need to develop alternative activities in order to fill the inherent knowledge gap in high-voltage subjects. This paper studies the implementation of H5P interactive content for teaching high-voltage electrical installation courses in higher education. This research addresses the pedagogical challenges of teaching complex technical concepts, equipment, and safety procedures in electrical engineering courses. A comprehensive set of H5P interactive resources was developed, allowing students to perform activities autonomously by interacting with the learning platform, obtaining a great user experience, self-assessment, and providing feedback to teachers on the teaching-learning progress. The materials covered fundamental topics such as substation design, protection systems, transmission line components, and transformation centers. The study involves the creation of interactive elements implemented during 2023 and 2024. The interactive materials were tested with students at the Linares School of Engineering at the University of Jaén, resulting in improved learning outcomes, with increased retention of technical concepts and improved practical skills compared to traditional teaching methods. Student feedback revealed high satisfaction levels regarding content accessibility and learning effectiveness. Additionally, faculty members reported reduced explanation time and increased student participation in theoretical and practical sessions. This research contributes to the enhancement and growth of knowledge on digital learning tools in engineering education, specifically addressing the unique requirements of high-voltage electrical installation courses.
