Protection against electric shock in electrical engineering didactic laboratories

Abstract

In order to rise safety level of the users in real laboratory environment related to the courses of electrical engineering the description and application examples of cover for laboratory screw terminals for use in research laboratories and experimental electrical systems and equipment is depicted in this paper. The main advantage of the described covers is the protection of laboratory personnel and students against direct contact to metal parts of terminal, which are under high voltage potentials. The paper points out the necessity for protection measures and contains examples of use of different covers for electrical machines, power converters, electric meters and other laboratory equipment.
