Aspects of the present disclosure are directed to increasing protection against electric shocks when a person is working on an electrical system. In some embodiments, the electrical system includes at least two different circuits and a safety module. An emergency signal input is provided on the safety module, and when an external emergency signal is received via the emergency signal input, the safety module shuts off a configured first circuit the associated switch and at least one further circuit via the associated switch if the safety module still receives the emergency signal at the emergency signal input after a predetermined period of time.

Electrical system comprising a plurality of electric circuits and anti-current protection equipment

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.

An apparatus and method for the measurement of a resistance of a switching contact of an electrical circuit breaker. A first resistance value across the circuit breaker is determined while the circuit breaker is grounded at both sides and the switching contact is closed. Further, a second resistance value across the circuit breaker is determined while the circuit breaker is grounded at both sides and the switching contact is open. The resistance of the closed switching contact is then determined based on the first resistance value and the second resistance value.
