Patent number: 7734380Abstract: A power management architecture for an electrical power distribution system, or portion thereof, is disclosed. The architecture includes multiple intelligent electronic devices (“IED's”) distributed throughout the power distribution system to manage the flow and consumption of power from the system using real time communications. Power management application software and/or hardware components operate on the IED's and the back-end servers and inter-operate via the network to implement a power management application. The architecture provides a scalable and cost effective framework of hardware and software upon which such power management applications can operate to manage the distribution and consumption of electrical power by one or more utilities/suppliers and/or customers which provide and utilize the power distribution system.Type: GrantFiled: September 19, 2003Date of Patent: June 8, 2010Assignee: Power Measurement Ltd.Inventors: Douglas S.

Patent number: 7342507Abstract: Power quality detection, monitoring, reporting, recording and communication in a revenue accuracy electrical power meter is disclosed. Transient events are detected by monitoring the wave shape of the electrical power and comparing deviations to a known threshold. Sags and Swells are detected by computing root mean square value over a rolling window and comparing the computed value with a known threshold. Harmonic frequencies and symmetrical components are quantified by a known algorithm and compared with a known threshold. Incoming waveforms are stored to memory. All recorded and computed data is moved to non-volatile storage via direct memory access transfer in the event that a power quality event jeopardizes the operating power of the meter. Further, the meter provides a power supply utilizing high and low capacitive storage banks to supply sufficient energy to survive short duration power quality events which jeopardize the meter's operating power.Type: GrantFiled: August 22, 2005Date of Patent: March 11, 2008Assignee: Power Measurement Ltd.Inventors: Rene T.

Patent number: 7265533Abstract: Systems and methods for monitoring power in a conductor. A flex circuit may include multiple layers including a voltage sensing layer, a coil layer, and a ground layer. The coil layer includes traces that form a coil structure around a conductor when the flex circuit is wrapped around the conductor. The coil layer generates a voltage that may be integrated to determine a current in the conductor. When the flex circuit is wrapped around the conductor, the voltage sensing layer is closest to the conductor. The voltage sensing layer forms a capacitor with the conductor. Using an adjustable capacitive voltage divider, the voltage of the conductor may be determined from a voltage signal received from the voltage sensing layer.Type: GrantFiled: June 15, 2004Date of Patent: September 4, 2007Assignee: Power Measurement Ltd.Inventors: Simon H. Lightbody, Michael E. Teachman, Colin N. Gunn, Benedikt T. Huber

Patent number: 7251570Abstract: Systems and methods for ensuring data integrity in a mesh network. A mesh network can include multiple RF devices. Transmitting quality data in or on the mesh network is improved using communication validation functions. The communication validation functions ensure a reliable communication network, preserve data during a network outage, and validate data. The communication validation functions can measure or control data quality within a communication and analysis network. The communication validation function operates to control data quality, for example, by measuring the quality of wireless links, ensuring the presence of redundant links, testing the ability of the mesh network to establish a backup communication path, generating alarms based on communication thresholds, tracking the communication path followed by communication packets, and identifying placement locations for additional RF devices.Type: GrantFiled: May 4, 2005Date of Patent: July 31, 2007Assignee: Power Measurement Ltd.Inventors: Martin A.
