Methods are provided for accelerating the insulation resistance measuring for determining an insulation resistance according to a pulse measuring method in an ungrounded power supply system. After indicating a target charging state of the network capacities available, a target point in time is calculated at which the network capacities have reached the target charging state. A first wait time is calculated from the current point in time as the difference between the target charging state and the current point. Alternatively, a target charging rate reflects a sufficiently stationary charging state of the capacitors, valid for measuring the insulation resistance. The target charging rate corresponds to the derivative of the first order of the target charging voltage and thus linked to the target point in time. Using the derivatives of the first order, a time difference is calculated as a second wait time.

A measuring arrangement and method are for measuring a loop impedance of a residual current loop of an active and protective conductor in an ungrounded power supply system. A device connected to a consumer point measures a conductor-to-ground voltage and computes loop impedance. An insulation monitoring device determines the insulation resistance in the system via a grounding device between the active and protective conductors on the feeding side. This grounding device selectively overrides one of the active conductors according to the control information of the measuring device via the communication channel and forms a residual current loop with impedance measured by interacting with the extended measuring device on the consumer side. Control information generated by the measuring device is telecommunicated to the grounding device. An insulation monitoring device equipped therewith may conduct a measurement of the loop impedance in the ungrounded power supply system in addition to insulation monitoring.

A method and an electrical circuit arrangement is for determining an insulation resistance of an ungrounded power supply system, which feeds electrical energy to the water-electrolysis installation. The fundamental idea of the method is based on predicting the insulation resistance of the ungrounded power supply system during an initial booting of the water-electrolysis installation and thus keeping the delay caused by the demineralization process as short as possible until the electrolysis process for subsequent booting processes of the electrolysis installation has been actually cleared. In a variation of the method, the electric conductance value and the temperature of the process water are additionally provided and recorded depending on the specific installation by the demineralization installation during the demineralization process. The result is a cost-efficient monitoring approach with a simple option for retrofitting for determining the insulation resistance of the ungrounded power supply system for the supply of water-electrolysis installations.

A first wait time is calculated from the current point in time as the difference between the target charging state and the current point. Alternatively, a target charging rate reflects a sufficiently stationary charging state of the capacitors, valid for measuring the insulation resistance. The target charging rate corresponds to the derivative of the first order of the target charging voltage and thus linked to the target point in time. Using the derivatives of the first order, a time difference is calculated as a second wait time.

Abrégé

A method and an electric circuit arrangement for determining a branch insulation resistance and a branch leakage capacitance of a line branch to be monitored in a branched, ungrounded power supply system having active conductors and a measuring voltage fed centrally by a controllable measuring voltage source and a residual current caused by the measuring voltage being registered using a current sensor in the line branch to be monitored. The centrally supplied measuring voltage is formed over a generator period having a characteristic signal form defined via the frequency composition. By this (frequency) modulation of the measuring voltage, information is transmitted from the central feed location of the measuring voltage to the current sensor disposed in the line branch to be monitored. Based on this information, the current sensor can establish with which resistance value the coupling circuit feeds the measuring voltage in the corresponding generator period, without another communication channel being required.

A method and monitoring device for selectively determining partial insulation resistance and partial system leakage capacitance of an outgoing line in a branched ungrounded power supply system monitored using an insulation monitoring device actively superposing a measuring alternating voltage on the ungrounded power supply system. Using an equivalent circuit diagram of the branched ungrounded power supply system as a basis, the partial insulation resistance having the current/voltage ratios applicable in linear systems are derived from the known measuring voltage and the inner resistance of the insulation monitoring device and from the total insulation resistance and the stationary partial current measured in the corresponding outgoing line and in the settled state. To calculate the partial system leakage capacitance, the temporal derivative of the measured non-stationary conductor-to-ground voltage is evaluated in conjunction with the non-stationary partial current and the previously determined partial insulation resistance.

Abrégé

A method and a measuring device for detecting a leakage current in an ungrounded, single-phase alternating-current power supply system. A variable test resistance is switched between one of the outer conductors and ground and starting from a minimally admissible test-resistance value, at least one of three support test-resistance values is determined as support locations. In an equivalent circuit of the modeled alternating-current power supply system, an equations system is set up for describing the dependency of currents and voltages. An extrapolation on the test-resistance value zero leads to a calculated test current which corresponds to the leakage current to be detected. Consequently, a ground fault situation may be simulated without actually causing a dangerous ground fault.

Abrégé

The invention relates to a device and a method for insulation monitoring including identification of a faulty outer conductor in a three-phase ungrounded power supply system. The fundamental idea of the present invention rests upon determining the phase angle between the measured mains voltage and the measured neutral-point voltage when presuming only one measurement of the mains voltage to ground at one of the outer conductors and one measurement of the neutral-point voltage to ground. The value of the thus determined phase angle is in one of three angle ranges which each extend over 120 degrees and are to be assigned to one of the three outer conductors so that the faulty outer conductor is determined. The faulty outer conductor is thus detected by measuring only one mains voltage in conjunction with the measurement of the neutral-point voltage by evaluating the phase between the two measured voltage.

The invention relates to a method, electrical circuit arrangements and insulation monitoring devices for an interference-resistant insulation monitoring of an ungrounded power supply system having a converter. Switching-frequent interfering signals, which are caused by operating the converter, are identified and assessed in a measured displacement voltage independently of the detection of a measuring signal in order to derive a switching (off) signal if required. Complementary thereto, an interfering resistance with respect to low-frequency interfering portions generated by the converter is attained by these low-frequency interfering portions being generated from a replica of a pulse width modulation signal of the converter and being suppressed sufficiently via subtraction that a monitoring without gaps (frequency) of the insulation resistance becomes possible.

The invention relates to a method for insulation fault location as well as to an insulation fault location system for an ungrounded power supply system. The main idea of the present invention rests upon the idea that while preserving a predetermined maximally admissible test current amplitude, a test current pulse duration of a test current is adaptively set such that all interfering values are eliminated in a captured differential current, in particular the leakage currents arising in consequence of large supply leakage capacitances. Should a test of the value of the final value of the differential current reveal that a test current threshold value has been exceeded, this exceedance can be seen as an indicator that the respective conductor section is therefore in the fault circuit.

The invention relates to a method and to an electrical protection device for detecting a disconnection of a protective conductor connection with a subsystem in ungrounded and grounded power supply systems and in a grounded power supply system comprising a converter system. The invention is based on the idea that the disconnection of the protective conductor connection with a subsystem will reduce the sum of the network leakage capacitances of the power supply system by the value of the network leakage capacitance of the subsystem. The necessary distinction between a subsystem in operation having a disconnected protective conductor connection and a shut-off subsystem is made by evaluating the current total power consumed via the power supply system. In the case of a converter system connected to the subsystem, the protective conductor disconnection is detected by examining the leakage current spectra that are characteristic of the converter system.

A method and a device for a galvanically isolated AC/DC-sensitive measurement of a residual current (ΔI), 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 (ΔI) and an oscillator signal that switches between a state 1 and a state 2. As a function of the residual current-driven magnetic field, times of stay of the oscillator signal occurring in states 1 and 2 are determined and an output signal proportional to the residual current is obtained from the ratio of the times of stay.

Abrégé

A method for monitoring and measuring an insulation resistance in ungrounded and grounded power supply systems includes the method steps of generating a periodic measuring signal, coupling in the measuring signal between active conductors of the power supply system to be monitored and ground, and detecting and evaluating measured values of the measuring signal. In one embodiment of the invention, the generated measuring signal is formed as a multi-frequency signal by the superposition of a finite number of harmonic oscillations with at least three harmonics. Alternatively, the multi-frequency signal can also be realized by means of a targeted, portioned construction of the signal shape in the time domain on the basis of a binary sequence optimization or by generating the measuring signal by means of the time-division multiplexing method.

Abrégé

A pulse generator circuit arrangement for the search for insulation faults in IT networks includes a rectifier circuit for transforming an IT network voltage into a DC intermediate circuit and switching elements having a trigger signal input for switching on and off a DC intermediate circuit voltage. A circuit device downstream of the switching elements generates a pulsed current to be supplied to the IT network. The circuit arrangement includes a control and evaluating logic for determining the insulation resistance of the IT network and also a circuit device for generating the pulsed current, which is formed as a current regulating device and allows a dynamic adjustment of the pulsed current depending on the determined insulation resistance.
