摘要： A system for testing and documenting the electrical wiring in a building, for example, comprises a Portable Circuit Analyzer (PCA) that is connected to the building's Load Center through an umbilical cord. The PCA is in wireless communication with a hand-held computer device, such as a personal digital assistant (PDA) as now widely available, provided with custom software according to the invention. The electrician connects the PCA in succession to each circuit in the building, operating each switch, and each fixture or appliance, while recording the test results of the circuit element on the PDA. The PCA measures the resistance and length of each circuit thus established. When the test process is completed, the PDA is enabled to generate a complete schematic diagram of the building, including, for example, an identification of the branch circuit to which each fixture, outlet, appliance, or other load or connection point is connected.

摘要： A device for use in locating a fault on a power line of a power distribution system includes: at least one sensor for measuring at least one property of the power line, and at least one output device in operative connection with the sensor to signal a state of the power line. The signaled state of the power line is determined from the measured property and indicates whether a fault has occurred in the power line. The output device can, for example, signal a current state or a previous state of the power line. The device can further include a controller in operative connection with the output device to control the operation of the output device based upon at least one of the current state or the past state of the power line. A device for use in measuring a property of power line of a power distribution system includes: a connector adapted to place the device in operative connection with the power line in the power distribution system without taking the power line out of operation; a sensor for measuring a property of the power line, and an output device in operative connection with the sensor to transmit a signal representative of the measured property.

摘要： An electrical continuity tester has a handheld housing having batteries, switch, test bulb, a probe and a power cord having a grounded plug on the end of the power cord. The handheld tester is used to first check that a common grounded outlet is wired properly by closing the switch and observing the test bulb. The test bulb should come on if the grounded outlet is wired properly. After the outlet has been verified, the probe can be used to touch any metal or conductive parts of any electrical device or appliance to verify that the metal part is properly grounded or wired to the hot side of the circuit. The cord and plug provides one connection for the tester and the probe provides the other connection.

摘要： A method and apparatus for locating a short between two nets in an electrical wire network of a microelectronic structure (e.g., chip, chip carrier, circuit card, etc.). A first net and a second net of the electrical wire are electrically shorted at an unknown point PS on the first net. Points PA and PB on the first net such are selected such that PS is located on a path between PA and PB along the first net. A constant current pulse source is electrically connected between PA and PB and is activated. Voltage drops VAB (from PA to PB) and VAC (from PA to a point PC on the second net) are measured. A length LAS of the path from PA to PS is calculated as a function of VAC/VAB. Computer graphics may be used to graphically display the location of the short within the microelectronic structure.

摘要： A fault is located in a power distribution system having a line frequency. The power distribution system includes a plurality of phases, at least one feeder, and each feeder includes at least one segment. The fault is located by detecting a faulted phase from the plurality of phases of the power distribution system. A measurement signal having a measurement frequency is injected into the detected faulted phase, the measurement frequency being a different frequency than the line frequency. The fault location is determined for a selected segment based on at least one measured residual current corresponding to the injected signal and a predetermined relative impedance of the power distribution system.

摘要： A system and method for locating a circuit defect, such as a short or an incipient open, in an electric circuit in a workpiece, such a Printed Circuit Board (PCB) or MultiChip Module (MCM). The circuit is connected to a device for sensitively measuring any resistance change. A thermal stimulus is applied to various subsets of the surface of the workpiece, the thermal stimulus being temporally modulated, and the resistance change measurement correlated with this modulation. By applying well-designed thermal stimulus subsets, resistance measurements may be logically combined which correspond to the plural thermal stimulus subsets. Further, the search region where the defect may be located may be iteratively refined. By measuring the time delay between the thermal stimulus and corresponding resistance change, the depth of a defect below the surface of the workpiece is further determined. Thus the system and method efficiently and accurately locates a defect in three dimensions, even if the workpiece is large, and the defect is small and underneath the surface.

摘要： A system for detecting arcing faults in an electrical distribution network having a line conductor carrying an electrical signal between a power source and a load, the system being capable of detecting series arcs, line-to-neutral arcs and line-to-ground arcs. The system includes a sensor coupled to the line conductor for monitoring the electrical signal and generating a sensor signal representing the electrical signal. The system generates an arc-indicative signal in response to the sensor signal having characteristics indicative of an arcing fault. The system can include a testing system in which a test wire is coupled to the sensor simultaneously with the line conductor and a test signal is periodically produced on the test line. The sensor simultaneously monitors the test signal and the electrical signal and produces a sensor signal representing both the test signal and the electrical signal when the test signal is present on the test line. The arcing fault detection system generates an arc-indicative signal in response to the sensor signal associated with either the test line or line conductor having characteristics indicative of an arcing fault. A diagnostic test integrator evaluates the status conditions of the test signal and the arc-indicative signal and generates a trip signal to trigger the interruption of the electrical signal in response to certain status conditions of the test signal and the arc-indicative signal.
