Abstract: A DC power distribution system and method includes a solid state remote power controller that connects a switching power source to a DC bus when the DC bus is switching power sources thereby providing a nearly uninterrupted power supply to the DC bus.

Abstract: A DC arc fault device and methodology includes acquiring a signal in response to a DC current. A software module identifies a parallel DC arc event when a difference between a maximum signal value and a minimum signal value exceeds a threshold. The software module also determines average signal values over multiple selected time periods and identifies a series DC arc event in response to the difference between the average values exceeding a predetermined threshold.

Abstract: An electrical fault locating system for distributing power from an input to a plurality of output channels provides fault detection and locating for each of the plurality of output channels. Each of the plurality of output channels is monitored by a fault detection circuit to detect the presence of an electrical fault. In response to a detected fault condition, the fault detection circuit isolates the output channel from the input and generates an output identifying the output channel on which the fault was detected. A fault locating device injects a high-frequency (HF) signal onto the input of the electrical system, the HF signal is distributed to each of the plurality of output channels, and the monitored reflection of the HF signal is monitored by the fault locating device to calculate a distance to the detected fault.

Abstract: An AC arc fault device and methodology includes acquiring a signal in response to an AC current and defining overcurrent regions that correspond to the alternating directions of the AC current and a normal region. A software module identifies a parallel AC arc event over a selected time period in response to multiple occurrences of the acquired signal moving into one of the overcurrent regions. The software module also determines average current values over multiple selected time periods and identifies a series AC arc event in response to the difference between the average values exceeding a pre-determined threshold.

Abstract: A method of detecting and indicating a presence of alternating current (AC) series arc fault events in current supplied by an AC electrical power source to an electrical load for the power source comprises the steps of: measuring positive and negative current through the load over a first sample cycle of the AC power to establish first measured positive and first measured negative current levels; determining the absolute value of the first measured positive and first measured negative current levels to establish a first absolute positive current level and a first absolute negative current level; adding the first absolute positive current level and the first absolute negative current level to establish a first sum current level; measuring positive and negative current through the load over a second sample cycle staggered from the first sample cycle to establish second measured positive and second measured negative current levels; determining the absolute value of the second measured positive and second measure

Abstract: The present invention is a generator control system where each generator in the system has an associated controller. Each controller communicates generator data or information with the other controllers in the generator control system. Each of the controllers includes a digital signal processor for analyzing the generator signal from the associated generator and information from the other controllers in the generator control system. The controllers each compare their generator signal with a system average and adjust the associated generator until the generators all supply equal amounts of power to the system.
