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.
