摘要： A system for locating a ground fault in an HRG power distribution system includes an HRG pulsing system having a ground fault sensor to detect a ground fault, a pulsing contactor to introduce a pulsing current into the power distribution system, and a controller to control the pulsing contactor to introduce the pulsing current into the power distribution system in response to a ground fault detection by the ground fault sensor. Current sensors in the power distribution system monitor three-phase current signals on conductors of the power distribution system, with the current sensors positioned on distribution networks in the power distribution system and at a protection device included on each respective distribution network. A processor associated with each protection device and operably connected to the current sensors thereat receives signals from the current sensors for identifying a location of a ground fault in the power distribution system.

摘要： A method for detecting an open-phase condition of a transformer having a grounded-wye high voltage side connection including monitoring current flowing in a neutral connection on the high voltage side of the transformer in real time by voltage relaying and current relaying to identify an open phase condition signature in a signal capable of characterizing change of current magnitude. A current signal may be injected onto the neutral terminal and the zero-sequence mode of the transformer monitored to detect an open-phase condition indicated by an increase in network impedance and decrease or elimination of the injection current.

摘要： A circuit interrupting device having an auto-monitoring circuit for automatically testing various functions and structures of the device. The auto-monitoring circuit initiates an auto-monitoring routine which, among other things, establishes a self-test fault during either the positive or negative half- wave, or both, of an AC power cycle and determines whether the detection mechanisms within the device properly detect the self- test fault. An early detection signal indicates that the self-test fault was properly detected without interfering with the normal operation of the detection circuitry and without causing a false trip within the device. Additional functionality of the auto-monitoring circuit permits automatic verification that the device is properly wired, that is, not miswired, and determines whether the device has reached the end of its useful life.

摘要： The invention concerns an interface for cutting off the power supply for any fault current Id ≤ 300 milliamperes such that: Id≥ IPE + k.Ih where IPE represents the current returning to the power source via the protective conductor connecting the exposed conductive parts to earth and Ih ( ≤ 10 or 30 milliamperes) represents the current returning to the power source by means other than via the protective conductor or via an active conductor. Current Ih is therefore likely to travel through a person. In this way, the interface protects people and property against ground insulation faults and against certain direct contacts independently of the earth of the exposed conductive parts and of external conditions. It also protects people in the event of a failure in the protection of an area using the same earth in case of a fault.

摘要： A fault detection system is provided for a power distribution system having at least first and second line conductors carrying AC currents that are out of phase with each other from a source to a load, and a common neutral conductor. The system includes an arcing fault current sensor comprising a coil wound on a hollow core and coupled to both of the line conductors in a manner that the electrical currents in the line conductors flow in opposite directions inside the hollow core, thus inducing in the coil an output signal that is a function of the difference of the electrical currents in the line conductors. A neutral current sensor produces an output signal representing the magnitude and phase direction of current in the neutral conductor. An arcing fault detection circuit includes a processor programmed to (1) respond to a change in the first output signal to analyze the second output signal to determine whether the change in the first output signal is attributable at least in part to current in a line-to-line circuit, (2) if the answer is affirmative, determine a scaling factor to be used to adjust the value of the first output signal, and (3) analyze the adjusted first output signal to determine whether an arcing fault has occurred and produce a trip signal in response to the detection of an arcing fault.
