Abstract: The present invention relates to a current sensor and to a method for detecting an electrical current flow. The current sensor comprises a magnetic core (104), which can be arranged around at least one electrical conductor (102) so that an electrical current flow through the conductor generates a magnetic field that is guided in the magnetic core, a first acceleration sensor (110) having a movable first seismic mass, wherein the first acceleration sensor (110) can be operated to generate a first sensor signal depending on a displacement of the first seismic mass, and a second acceleration sensor (112) having a movable second seismic mass, wherein the second acceleration sensor (112) can be operated to generate a second sensor signal depending on a displacement of the first seismic mass, wherein the first and the second acceleration sensor are arranged so that the first and the second seismic mass can at least partly be penetrated by the magnetic field guided in the magnetic core, and wherein the second seismic mass is provided with a magnetically active element by means of which the second seismic mass is displaceable in response to the magnetic field guided in the magnetic core so that a difference between the first sensor signal and the second sensor signal forms an output signal depending on the electrical current flow through the conductor.

Abstract: The present invention relates to a monitoring device and a method of monitoring an impedance of a protective conductor. A first voltage divider is arranged between a first input terminal and a second input terminal, which can be connected to a voltage source. The first voltage divider comprises a series connection of a first resistor and a second resistor, the second resistor corresponding to a threshold value of the impedance of the protective conductor. A second voltage divider comprises a series connection of a third resistor and a bridge diode, and is connected with a first end of the third resistor to the first resistor, and is connectable with a second end to the protective conductor. A measuring device is connected between a first node that is arranged between the first resistor and the second resistor, and a second node, which is arranged between the third resistor and the bridge diode. A bridge voltage is detected between the first and second node if the impedance of the protective conductor is higher than the second resistor.
