Considerations regarding the new requirements for the evaluation of rotating electric machines with increased safety protection type “e”

Abstract

The evaluation of explosion-proof electrical equipment for certification is particularly important given the risk of explosion and must be minimized. This in order to ensure the safety of life, health of workers, to prevent damage to goods and the environment when they meet the essential security requirements at European level. Directive 2014/34 / EU states that equipment used in explosive atmospheres must be designed to operate without endangering the environment for which it is intende. This paper proposes the study and evaluation of the requirements for the evaluation of rotating electric machines with increased safety protection type “e”. The rotating electric machines with increased safety protection type “e”, in order to comply with the explosion protection, it must meet certain requirements given by the standard SR-EN 60079-7.
