摘要： A method and apparatus are provided for detecting a fault on a power line carrying a line parameter such as a load current. The apparatus monitors and analyzes the load current to obtain an energy value. The energy value is compared to a threshold value stored in a buffer. If the energy value is greater than the threshold value a counter is incremented. If the energy value is greater than a high value threshold or less than a low value threshold then a second counter is incremented. If the difference between two subsequent energy values is greater than a constant then a third counter is incremented. A fault signal is issued if the counter is greater than a counter limit value and either the second counter is greater than a second limit value or the third counter is greater than a third limit value.

摘要： To prevent unnecessary power outages, and to remove feeder lines from service only when certain hazardous fault conditions occur, a load analysis system including an apparatus and method, monitors the load level of a feeder line and determines the presence of any arcing on the feeder line. In a two stage load pattern analysis, the presence of arcing and load current level changes are used to discriminate high impedance, low current conditions including a downed conductor, a broken and dangling conductor, a tree or object contact with the feeder line, overcurrent activities, and normal switching events such as recloser operation. The load analysis system also provides output commands including wait, alarm, trip-ready, trip and normal, depending upon which status is diagnosed.

摘要： A method and apparatus are provided for detecting an arcing fault on a power line carrying a load current. Parameters indicative of power flow and possible fault events on the line, such as voltage and load current, are monitored and analyzed for an arc burst pattern exhibited by arcing faults in a power system. These arcing faults are detected by identifying bursts of each half-cycle of the fundamental current. Bursts occurring at or near a voltage peak indicate arcing on that phase. Once a faulted phase line is identified, a comparison of the current and voltage reveals whether the fault is located in a downstream direction of power flow toward customers, or upstream toward a generation station. If the fault is located downstream, the line is de-energized, and if located upstream, the line may remain energized to prevent unnecessary power outages.

摘要： A method and apparatus are provided for detecting an arcing fault on a power line carrying a load current. The apparatus monitors, compiles and analyzes sample parameters taken from successive cycles of the power line load signal indicative of power flow and possible fault events on the line, such as voltage or load current. The analyzed sample parameter is then used to determine a normal parameter corresponding to a normal load pattern for the line. The normal load parameter is extracted from the compiled sample parameter data, and the resulting difference signal waveform has a magnitude value which changes in amplitude corresponding to the load-extracted data which is used to determine whether a fault exists on the power line.

摘要： An expert detection system includes a method and apparatus for detecting high impedance faults occurring on a distribution circuit coupled to an AC power source. Based upon an expert's knowledge of high impedance fault behavior and the performance of various fault detection techniques, the expert forms a belief as to whether a high impedance fault has indeed occurred. The expert's beliefs may be adjusted with an elliptic formula, and then used to weight the status output of each technique. The weighted multiple technique outputs are combined to determine whether a high impedance fault has occurred. The expert's beliefs are calibrated during initial start-up by comparison with a confirmed performance history of the detector using a scoring rule. The belief calibration may be included during operation to provide on-line adaption of the expert detector to the changing situations of the distribution circuit.

摘要： A method and apparatus are provided for detecting an arcing fault on a power line carrying a load current. The apparatus monitors and analyzes the load current to obtain frequency components. The analyzed load current is then compared to frequency components of an arcing fault model spectrum to determine whether an arcing fault exists on the power line. If the difference between the analyzed load current and the model spectrum is less than a selected error value, then an arcing fault exists on the power line. Otherwise, no arcing fault exists and conditions are normal on the line.
