AIM OF THE COURSE
The course aims to provide students with the notions relating to the main directives applicable to the electrical safety of systems and devices in the workplace as well as the main tests and checks for the safety of electrical systems. In particular, the risks deriving from overvoltages and overcurrents (for example: short circuits, lightning, electric arcs, electric fires), the analysis of the components that can be used for the protection of people and systems (automatic circuit breakers, differentials, magnetothermic, disconnectors, fuses, SPD, AFDD). The risk assessment in the workplace connected to electricity will be addressed with a focus on those deriving from electromagnetic fields and explosive environments.
The main schemes of electrical systems will be addressed, including SELV, PELV, FELV systems and the earthing system, as well as the main types of electrical system faults and measures for the protection of people and the systems themselves.
Information will be provided on the measurement of the main electrical quantities and on the main checks of the electricity network. Power quality elements (e.g. voltage dips, variations in mains frequency, flicker, harmonics) and disturbances introduced into the network. Power factor correction.
