Abstract : This article presents a technical study dedicated to the rehabilitation of test benches IV, V and VI of the electrotechnical laboratory of ISPT-LikasiFaced with obsolete equipment and the requirements of the Competency-Based Approach (CBA), the rehabilitation of test benches IV, V, and VI in the electrical engineering laboratory has become an imperative necessity due to the degradation of legacy equipment. The initial assessment revealed structural obsolescence where mechanical wear of components and fragile wiring have become major risk factors. The main objective of this project is to restore operational reliability while adapting these tools to contemporary technological requirements. From a safety perspective, the absolute priority is bringing the installations into compliance with current electrical standards. This entails the systematic replacement of archaic protection systems with high-sensitivity residual current circuit breakers (RCCBs) and the installation of centralized emergency stop devices. These measures aim to eliminate any risk of electrocution for students and researchers, guaranteeing a safe and professional working environment. The modernization also aims to drastically improve metrological accuracy, often compromised by aging analog measuring instruments. The integration of modern sensors, capable of providing data with low uncertainty, is central to this transformation. The shift to digital instrumentation allows for greater accuracy in measurements, an essential condition for any rigorous scientific research. The project includes a transition to automated data acquisition systems. By replacing manual meter readings with interfaces connected to specialized software, the laboratory reduces human transcription errors. This digitalization facilitates realtime results analysis, transforming raw data into instantly usable graphs and reports. The pedagogical aspect of the modernization is equally crucial for enhancing practical experience. These renovated benches allow students to work with cutting-edge technologies, such as high-performance static converters and programmable control systems. This upgrade ensures a strong connection between the theoretical training received in the classroom and the realities of industrial fieldwork. The durability of the installations is ensured through the selection of robust and easily replaceable components. By structuring the wiring in a modular fashion and using standardized connectors, future maintenance operations will be easier and less expensive. This preventative approach significantly extends the service life of IV, V, and VI test benches. Automating startup and protection sequences is another modernization lever. By integrating programmable logic controllers (PLCs),The laboratory secures complex procedures, thus preventing overloads or mishandling during the power-up phases of rotating machines or transformers. Energy management within the laboratory will also benefit from this upgrade. Improved control of electrical parameters will allow for testing with optimized energy consumption and reduced heat loss. This eco-responsible approach modernizes the institution's image while reducing long-term operating costs. The implementation of this project requires rigorous planning, including strict testing phases before any commissioning. Each stage of the upgrade must be documented in a control report, ensuring that the accuracy of the results is validated by calibration in accordance with industry standards. Rigorous execution during this acceptance phase is the cornerstone of the project's sustainability. The modernization of test benches IV, V, and VI transforms an aging space into a center of excellence in electrical engineering. This project is not limited to a simple refurbishment but represents a true technological upgrade. Thanks to this intervention, the laboratory is equipped with the necessary means to meet the security and precision challenges required by modern research and teaching.
