The aim of the invention is to prevent undesired false triggering of a safety device, which protects a person from electric shock as a result of unintentional contact with voltage-carrying or current-carrying parts. This aim is achieved in that a triggering sensitivity (E) of the safety device is changed depending on a determined body resistance (R) of the person wearing the safety device.

Safety device for work on electrical systems

Various aspects of the present disclosure are directed to a system for increasing the protection against electric shocks of a person working in proximity to an electrical system. In one example embodiment, the system includes a plurality of first radio terminals, via each of which a radio link for receiving an emergency signal can be established. The system further including a protective device to be worn by the person and for detecting an electrical body current. The protective device including a second radio terminal that, in the event that an unacceptable body current is detected, outputs and transmits an emergency signal via a radio link established between one of the first plurality of radio terminals and the second radio terminal.
