A method for controlling a charging apparatus of a vehicle, in particular an electric or hybrid vehicle, wherein the charging apparatus has a charging device including a protection and monitoring device. The vehicle includes a high-voltage on-board power system and an electrical energy storage apparatus connected to the high-voltage on-board power system. The method includes electrically connecting the high-voltage on-board power system to charging connections of an energy supply system by the charging apparatus. The charging connections include a neutral conductor, a protective conductor and at least one phase conductor. A protective conductor resistance is detected between the neutral conductor and the protective conductor by feeding in a test current by the protection and monitoring device. A frequency of the test current is filtered out of the compensation frequency range on a narrowband basis.

A combined monitoring device for insulation-resistance monitoring and protective-conductor-resistance monitoring in a power supply system includes a grounded power supply system and an ungrounded power supply system, the combined monitoring device having a coupling circuit for being coupled to one or several active conductors of the grounded power supply system via coupling points, the combined monitoring device including an active monitoring device with a first operating mode for monitoring an insulation resistance in an ungrounded network state of the power supply system and a second operating mode for monitoring a protective-conductor resistance in a grounded network state of the power supply system, the combined monitoring device having an evaluation unit switchable between the first and second operating modes as a function of the ungrounded or grounded network state and configured for testing the insulation resistance in the first operating mode and the protective-conductor resistance in the second operating mode.

A ground fault circuit interrupter with a residual current device is suggested which comprises a tripping characteristic having a combined time-current curve that implements a minimum tripping time value of a first time-current curve and a second time-current curve for each current value.

A method and a device for a galvanically isolated AC/DC-sensitive measurement of a residual current (&#x394;I), includes a component sensitive to magnetic fields which switches between at least two states in the course of oscillation. A magnetic field is formed in a sphere of action of the component sensitive to magnetic fields due to the residual current (&#x394;I) and an oscillator signal that switches between a stateand a state. As a function of the residual current-driven magnetic field, times of stay of the oscillator signal occurring in statesandare determined and an output signal proportional to the residual current is obtained from the ratio of the times of stay.

A method and device for monitoring insulation and fault current in an electrical alternating current network. The differential current formed by vectorial addition is detected between at least two network conductors. Load-cut occurs when the differential current exceeds a specific threshold value. In order to increase safety and to protect human beings, the amount of alternating current contained in the differential current is detected as a first network variable, and the network alternating current between at least both network conductors and between at least one network conductor and an equipotential bonding conductor or a neutral conductor is detected as a second network variable. The product between the amplitude of the amount of alternating current contained in the differential current and the cosine of the phase angle &phgr; between both detected network variables is determined as a measure for the resistive fault current of the network and load cut-out occurs when the determined product exceeds a specific threshold value. The product can be calculated directly or, even better, it can be determined indirectly without knowledge of the individual variables. One particular advantage of this technique is that, by including DC components of the differential current, it enables work with all different types of currents in view of the fact that alternating current networks nowadays mainly consist of a large number of alternating current components which, like resistive AC components, involve fault currents endangering the lives of human beings. Thus, it is possible to ensure simultaneous protection of human beings and installations.
