摘要： A method of detecting an arc fault in a power circuit includes injecting an AC-signal into the power circuit and measuring a response signal that is related to the injected AC-signal in the power circuit. The method further includes determining a frequency response of the power circuit from the response signal, analyzing the frequency response, and identifying a preferred frequency. A signal related to AC-current flowing in the power circuit within the preferred frequency range is measured and an occurrence of an arc fault in the power circuit is signaled depending on the measured signal. A system for detecting an arc fault is designed to perform a method as described before.

摘要： An insulation detector for highly accurately detecting or measuring, with a simple configuration, insulation resistance of a load or an apparatus to a ground or a housing and connected to an electric apparatus including one or both of an intra-apparatus capacitor and a battery, the insulation detector including an intra-insulation detector capacitor, a voltage detecting unit that detects a voltage of the intra-insulation detector capacitor, and a current-path forming switch for connecting the ground or the housing, the intra-apparatus capacitor, and the intra-insulation detector capacitor in series and forming a current path including insulation resistance of the electric apparatus. The insulation detector measures the insulation resistance by measuring a time constant of a change in the voltage of the intra-insulation detector capacitor. A capacitance value of the intra-insulation detector capacitor is a value negligible in the measurement of the insulation resistance compared with a capacitance value of the intra-apparatus capacitor.

摘要： Provided is a control system that can appropriately determine whether or not supply of power to a load is abnormal, and can specify a detailed reason of the abnormality. A control circuit supplies power to a load and shuts off the supply of power in accordance with a power supply/shutoff instruction to supply or shut off power from a battery to the load. The power supply/shutoff instruction is output from a microcomputer to the control circuit. A control unit determines whether or not the supply of power from the battery to the load is abnormal, based on (i) whether the power supply/shutoff instruction output from the output unit is to supply power or shut off the supply of power, (ii) the value of a current flowing from the battery to the load, and (iii) the value of a voltage applied to the load, and specifies a reason of the abnormality.

摘要： A fault location detection method includes detecting an EMI signal and analyzing the spectral content of the electrical signal to identify a fault. A location recorder records the location of the system when the EMI signals are detected and a processor analyses the EMI signals and records the location of the system to determine a location of the fault. A memory includes an aerial photograph of a geographic location within which faults are to be detected and wherein the processor overlays the position of the faults on the aerial photograph. In addition, a transparent intensity map is superimposed onto a satellite photo of a geographic location and this is displayed to a user.
