Electric arc hazards - an introduction (Sweden)

The course gives you knowledge about how arcs occur and behave. We look at how to think to bring down the event energy in an arc. The course deals with risk prevention measures that prevent or limit arcs, such as barriers, disconnection of equipment, setting of protection and types of protection and disconnection of equipment that contributes to arc short-circuit currents.

This course teaches you about how electric arcs develop and behave. We learn about how to go about reducing the incident energy in an electric arc. The course covers risk prevention and reduction through factors such as establishing barriers, disconnecting equipment, installing protective devices, different types of protective device, and disconnecting equipment that contributes to electric arc short-circuit currents.

Target group

Personnel who may be exposed to electric arcs during their work, and personnel who design and operate electrical installations.
