Patent number: 8165834Abstract: A method of monitoring the electrical power in multiple branch circuits of an AC electrical power distribution system comprises monitoring at least one voltage common to said multiple branch circuits using a main meter unit, monitoring currents of the multiple branch circuits using multiple current cards that receive a plurality of current inputs from current transducers in the multiple branch circuits, sampling the monitored voltage in the main meter unit and the monitored currents in the current cards multiple times in each cycle of the AC power signal, determining the magnitudes and angles of spectral components of the sampled current in the current cards, sending data representing the magnitudes and angles of at least selected spectral components from the current cards to the main meter unit, and storing the voltage samples and the magnitudes and angles of at least the selected spectral components in the main meter unit.Type: GrantFiled: January 3, 2011Date of Patent: April 24, 2012Assignee: Schneider Electric USA, Inc.Inventors: Avery Long, Ronald W.

Publication number: 20110158244Abstract: Systems, devices, and computer readable media for optimizing serial communication networks provide an intelligent network gateway through which network data flows. Systems and devices monitor network requests for data packets supplied by slave computing devices, examine the supplied data packets, and copy the supplied data packets to a memory device. The supplied data packets are delivered to a first requesting network device and when an additional network request for the data packets is made by a second requesting network device the data packets are delivered from the memory device to the second requester in response to the additional network request without interrupting the slave computing device to redundantly supply the data packet. Polling by multiple requester devices for redundant data from slave computing devices is avoided. Communication response times are improved, data caching is provided for devices that have no logging memory, and optimum communication settings can be automatically determined.Type: ApplicationFiled: December 28, 2009Publication date: June 30, 2011Applicant: SCHNEIDER ELECTRIC USA, INC.Inventors: Avery Long, Timothy Curray

Patent number: 7528595Abstract: A three-phase monitoring system for detecting and dynamically correcting wiring errors in an electrical circuit. The system includes a voltage divider circuit and a current transformer circuit connected to three voltage channels and three current channels, respectively. Samples of the voltages and currents are held in respective sample and hold circuits, which are provided to an analog multiplexer. The analog multiplexer is controlled by a processor, and is coupled to gain and filter circuitry, sample and hold circuitry, and to an analog-to-digital converter (ADC). The ADC is connected to the processor, which analyzes the power factor for a given voltage/current pair. If the power factor is outside of an expected range, the processor dynamically changes the addresses assigned to the channels such that the data arrives in the processor in an expected sequence.Type: GrantFiled: May 16, 2006Date of Patent: May 5, 2009Inventor: Avery Long

Patent number: 7177771Abstract: A power metering apparatus meters a power signal in a powered system. A low-pass filter receives the power signal and outputs a filtered signal. The filter implements a corner frequency programmable based on a first clocking signal and anti-aliases high frequency components of the power signal. An A/D converter receives the filtered signal and outputs a digital signal. The A/D converter samples the filtered signal according to a system clock based on a second clocking signal. A clocking element generates and outputs each of the first clocking signal and the second clocking signal. The first clocking signal is synchronous with the second clocking signal.Type: GrantFiled: March 28, 2005Date of Patent: February 13, 2007Assignee: Square D CompanyInventor: Avery Long
