摘要
The invention concerns a voltage bulb (20) for an electrical system part (11) of an electrical system (10) or an electrical system (10) with an electrical building element (21),which is designed to be electrically connected to an active part (14) of the electrical system part (11) or to the electrical system (10) and to collect a voltage related to the active part (14) and a first wireless signal unit (22),electrically connected to the electrical building element (21) and so arranged that the first wireless signal unit (22) emits a warning signal (30) into an environment (32) around the first wireless signal unit (22) when the electrical building element (21) takes a voltage from the active part (14), so that the warning signal (30) can be received by a second wireless signal unit (51) in the environment (32). The invention also concerns a voltage warning system (60) with the voltage warning system (20) and an electrical system (10) with the voltage warning system (60).
