  • Patent number: 9476930
    Abstract: A method determines a location of a fault in a faulty feeder section of an ungrounded power distribution system based on a type of the fault and the type of the faulty line. The method determines, if the faulty line is the lateral and the fault is phase-to-phase or double-phase-to-ground fault, the fault at a first point on an un-faulty phase of the lateral where a fault current equals a load current. The method determines, if the faulty line is the lateral and the fault is the three-phase fault, the location of the fault at a point with a minimal difference between imaginary parts of equivalent fault impedances. The method determines, if the faulty line is the mainline, the location of the fault at a point partitioning the faulty segment on two sub-segments with a ratio of lengths determined based on the voltages at the buses of the faulty segment.

  • Patent number: 9476931
    Abstract: A location of a fault in an ungrounded power distribution system is determined by identifying a faulty feeder section and a type of the fault using voltages and currents measured before and after the fault and selecting the location of the fault at the faulty feeder section by testing a relationship of a current over a voltage measured at boundaries of the faulty feeder section after the fault with different equivalent admittance matrices of the faulty feeder section determined for different candidate locations of the fault of the determined type. The fault is a short-circuit fault including one or combination of a single-phase-to-ground fault, a phase-to-phase fault, a double-phase-to-ground fault, a three-phase-to-ground fault, and a phase-to-phase-to-phase fault.

  • Patent number: 9415407
    Abstract: An electrostatic coating apparatus includes: a spray gun configured to spray a coating material onto a coating object; a voltage application device configured to apply a high voltage to the spray gun; and a current measurement device configured to measure electric current flowing through the spray gun. When the spray gun, which is in a state of not spraying the coating material onto the coating object and is under application of the high voltage from the voltage application device, is located at a distance from the coating object, the electric current flowing through the spray gun is measured by the current measurement device. A grounded state of the coating object is checked, based on the measured electric current. This shortens the time required for checking the grounded state, while allowing for downsizing and simplified configuration of production equipment and reduction of equipment cost.
