A method and a balancing circuit (10) for balancing an ungrounded direct-voltage power supply system (2) are disclosed. In a detector circuit (12), a faulty active conductor (L-) is detected in which a largest leakage current to ground (PE) flows because of a lowest insulation resistance (Rf-). The faulty active conductor (L-) is coupled to the balancing circuit (10) by means of a switching device (14), the largest leakage current being compensated by means of an open-loop and closed-loop control device (16) of the balancing circuit (10) without reducing the insulation resistance (Rf+) of the other active conductor (L+). Furthermore, an enhanced insulation monitoring device (30) is provided for monitoring an ungrounded direct-voltage power supply system having a balancing circuit (10).
A balancing device and method for balancing an ungrounded power supply system are disclosed. The balancing device is switched multipolarly between the corresponding active conductors and ground potential and comprises a voltage measuring device for each active conductor for detecting a corresponding conductor-to-ground voltage, a microcontroller which evaluates the conductor-to-ground voltages, a PFC controller for each active conductor, the PFC controller reproducing a control impedance in such a manner that a voltage balance is set between the active conductors, and further comprises an intermediate circuit which stores energy converted in the control impedances and a converter which outputs the energy stored in the intermediate circuit to the power supply system.
Methods and devices for minimizing a possibly corroding DC protective-conductor current for a DC system grounded via a protective conductor designed as a foundation ground electrode with connected SK 1-operating equipment. Balancing includes feeding a balancing current to a casing of the class I operating equipment at a ground terminal via an output circuit between a fault-free active conductor and ground terminal, a balancing-current polarity and amplitude set such that the DC protective-conductor current is minimized in the foundation ground electrode. In contrast to DC balancing, DC compensation means a compensating current is fed to the casing at the ground terminal of the class I operating equipment via an output current between the faulty active conductor and the ground terminal. Regarding the polarity and the amplitude, the compensating current is such that the DC protective-conductor current is minimized in the foundation ground terminal. The balancing current and the compensating current are set via switching of power sources, resistors or a PWM signal.
A method and devices for testing and monitoring the continuity of a PEN conductor for a three-phase TN-C-S power supply system to which operating equipment is connected via a single or three phases. As intended by the invention, a voltage is measured for this purpose at a virtual star point set up according to the invention at operating equipment using three-phase machine terminals, and the measured star-point voltage is evaluated. Should the star-point voltage exceed a critical voltage, the operating equipment is disconnected. The invention therefore does not require a constructively difficult installation of a local reference ground. For operating equipment with single-phase machine terminals, a load voltage is measured in a first and a second load case along with a computation of a loop impedance from the voltage change and a residual-current change. The thus determined loop impedance value allows drawing a conclusion on whether a functional PEN conductor is present.

METHODS FOR ACCELERATING THE INSULATION RESISTANCE MEASUREMENT IN AN UNGROUNDED POWER SUPPLY SYSTEM
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 insulation monitoring arrangement for insulation monitoring of an electric installation operated using a supply direct voltage and has a first insulation resistance between the positive active conductor and ground and a second insulation resistance between the negative active conductor and ground as well as a functional grounding between the negative active conductor and ground by a ground resistance. The method involves measuring a ground current, which flows in the path of the functional grounding, by means of a DC measuring device; measuring the supply direct voltage by means of a voltage measuring device; computing the first insulation resistance from the supply direct voltage divided by the ground current by means of a computing unit; the condition is valid during operation of the electric installation that the second insulation resistance being at least 100 times greater than the ground resistance.
A method and an insulation monitoring device for insulation monitoring with network balancing in an ungrounded direct voltage system involves a measurement of conductor-to-ground voltages by means of voltage measuring devices; a computation of insulation resistances specifically for a conductor; and a compensation of an asymmetrical voltage between the conductor-to-ground voltages by means of a control circuit. A combination of an insulation monitoring function and network balancing based on a digital control circuit with the degree of asymmetry (asymmetrical factor) as control variable is provided. The asymmetrical voltage is compensated permanently via a suitable assessment of a (voltage) control error by means of a controller, and the resistance setting value required therefor is detected as a manipulated variable for one of the variable resistances.
A method for suppressing EMC disturbances in a DC charging station for electric vehicles with at least one converter circuit having semiconductor circuit breakers which are actuated via a pulse curve using a switching frequency.

The method is applicable analogously for a charging device in an electric vehicle.

Method and device for insulation monitoring of a water-electrolysis installation
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.

Methods for accelerating the insulation resistance measurement in an ungrounded power supply system
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.
An electric circuit arrangement and to a measuring method for the galvanically separate, AC/DC-sensitive residual-current measurement, the measuring method including registering a residual current (Id) by means of a measuring current transformer having a toroid and precisely one secondary winding; supplying power to the secondary winding and generating a time-modulated, binary measuring signal (V) having a corresponding dwell time (Th, T1) in a first state (S1) and a second state (S2) by means of a driver circuit having an oscillation circuit; evaluating the dwell times (Th, T1) by means of a computing unit and outputting a residual-current measured value (Im, I'm) by a data interface, wherein the driver circuit having the oscillation circuit forms an integral structural unit in the form of a driver module, which is supplied with a shared, unipolar operating voltage (Ub) by a power-supply device together with the computing unit.

Method and electric circuit arrangement for determining a branch insulation resistance and a branch leakage capacitance in an ungrounded power supply system
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.

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 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 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.

Device and method for insulation monitoring in a power supply system including a high-resistance grounded neutral point
A device and method is for insulation monitoring in a power supply system composed of a main system including a neutral point that is high-resistance grounded via a neutral-point resistance and, optionally, of at least one subsystem, wherein the main system and the subsystem each have a differential current measuring device for registering a differential current.
The invention is based on feeding a measuring signal into the optionally branched HRG system via an active measuring method and registering the fault current driven by the measuring signal in the outgoing power feeds to be monitored by means of a differential current measurement and using the registered fault current in an evaluating device to determine the total insulation resistance of the power supply system and to determine the partial insulation resistances of the main system and potentially present subsystems. Furthermore, the insulation monitoring device can be employed for insulation fault location.
