摘要： The invention relates to a system for protecting an electrical source or an electrical load, having a module comprising an input and an output, and an electronic safety device for the load that can be connected to the source. The module also comprises a voltage monitoring unit, a current monitoring unit, and semiconductor switching units and controllers associated therewith. According to the invention, in order to selectively apply the protection to the source or the protection to the load, a unit for electrical mirroring on the circuit side is provided so that in the event of source protection, the current monitoring unit is applied at the input end and the voltage monitoring unit is applied at the output end, and in the event of load protection, the voltage monitoring unit is applied at the input end and the current monitoring unit is applied at the output end.

摘要： The invention relates to a device for detecting electrical currents on or in the vicinity of electrical conductors with at least one Reed switch as a magnetically responsive switch, which is arranged in the vicinity of the electrical conductor such that, when there is a significant current flow through the conductor, the magnetic field created triggers the switch and initiates an evaluation electronics connected to the switch. For the detection of surge current variables and the differentiation between long-term pulsed currents and short-term pulsed currents, a plurality of Reed switches are arranged at a predetermined distance from the electrical conductor, wherein the evaluation electronics determines the response and the switching times of the respective Reed switches, determines die surge current variable from the allocation of the determined values to the respective Reed switch and the pulse form from the switching time, wherein, for the purpose of adjusting the response behavior, at least one of the Reed switches comprises a shielding for influencing the magnetic field acting on the respective Reed switch.

摘要： The invention relates to a method for detecting electrical currents on or near electrical conductors with at least one reed switch as a magnetically responsive switch, which is arranged near the electrical conductor such that when there is a significant current flow through the conductor, the magnetic field created triggers the switch and initiates evaluation electronics connected to the switch. For the detection of surge current variables and differentiation between long-term pulsed currents and short-term pulsed currents, a plurality of reed switches is arranged at pre-determined, different, increasing distances from the electrical switch, the evaluation electronics determining the response and the switching times of the respective reed switches. The surge current variables are determined from the association of the determined values with the respective reed switch and the pulse shape from the switching time.
