Latest Patents

One of Hong Chun's latest patents focuses on "Voltage derivative and zero-sequence broken conductor detection." This invention allows for the identification of a broken electrical conductor by monitoring the rate of change of phase voltage and zero-sequence voltage at various points along the conductor. Intelligent electronic devices (IEDs), such as phasor measurement units, are utilized to gather measurements and calculate synchrophasors. These synchrophasors enable a central controller to determine which two continuous IEDs measure rates of change of voltages of opposite polarities, indicating the location of the broken conductor. Additionally, the system can identify IEDs where one exhibits a zero-sequence voltage magnitude exceeding a predetermined threshold for a specific duration, while the other does not.
