METHOD AND ELECTRIC CIRCUIT ARRANGEMENT FOR DETERMINING A BRANCH INSULATION RESISTANCE AND A BRANCH LEAKAGE CAPACITANCE IN AN UNGROUNDED POWER SUPPLY SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240012042 titled 'METHOD AND ELECTRIC CIRCUIT ARRANGEMENT FOR DETERMINING A BRANCH INSULATION RESISTANCE AND A BRANCH LEAKAGE CAPACITANCE IN AN UNGROUNDED POWER SUPPLY SYSTEM
Simplified Explanation
The abstract describes a method and an electric circuit arrangement for determining the insulation resistance and leakage capacitance of a line branch in a branched, ungrounded power supply system. The system includes active conductors and a centrally fed measuring voltage source. A controllable measuring voltage source supplies the measuring voltage, and a current sensor registers the residual current caused by the measuring voltage in the line branch.
Key points of the patent/innovation:
- The measuring voltage is formed over a generator period with a characteristic signal form defined by the frequency composition.
- The measuring voltage is modulated by the frequency to transmit information from the central feed location to the current sensor in the line branch.
- The current sensor can determine the resistance value of the coupling circuit that feeds the measuring voltage in the corresponding generator period based on this information.
- No additional communication channel is required for this transmission of information.
Potential applications of this technology:
- Power supply systems: This technology can be applied in various power supply systems to monitor the insulation resistance and leakage capacitance of line branches.
- Electrical maintenance: It can be used for maintenance purposes to detect any insulation faults or leakage issues in line branches.
- Industrial applications: This technology can be implemented in industrial settings to ensure the safety and efficiency of power supply systems.
Problems solved by this technology:
- Insulation resistance monitoring: The method and circuit arrangement provide a solution for accurately determining the insulation resistance of line branches in a power supply system.
- Leakage capacitance detection: The technology also enables the detection of leakage capacitance in line branches, which can help identify potential issues in the system.
- Communication efficiency: By using frequency modulation of the measuring voltage, information can be transmitted without the need for an additional communication channel, simplifying the system design.
Benefits of this technology:
- Accurate monitoring: The method allows for precise determination of insulation resistance and leakage capacitance, providing accurate information about the condition of line branches.
- Cost-effective: By utilizing the existing measuring voltage source and current sensor, the technology eliminates the need for additional equipment, reducing costs.
- Simplified communication: The frequency modulation of the measuring voltage enables the transmission of information without requiring a separate communication channel, simplifying the system setup and operation.
Original Abstract Submitted
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.
