A new integrated tool for exercises on the design of electrical installations using a microcomputer

An innovative approach using computer-aided design tools to support the teaching of electrical installations through hands-on design exercises is described. It is implemented by an integrated package with all the built-in facilities which guide engineers/students step by step to complete the design of two sizeable electrical installations. The dedicated file structure enables students to get direct access to the building information, details of each type of load and the technical parameters of all the electrical parts required for the design exercise. The combination of full design, partial design and automatic design eliminates routine and repetitive design studies and also accelerates the design and learning process. Errors made by the user are prompted on the spot and the userʹs performance is evaluated automatically through error logs and a demerit point system. Simulation tests enable the users to visualize the performance of the installations designed by them under a series of loading conditions, and to experience any consequences due to the design errors.
