Patent number: 7188003Abstract: 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. The IED's are linked via a network to back-end servers. 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. Security mechanisms are further provided which protect and otherwise ensure the authenticity of communications.Type: GrantFiled: January 5, 2004Date of Patent: March 6, 2007Assignee: Power Measurement Ltd.Inventors: Douglas S. Ransom, David A. Chivers, J. Bradford Forth, David W. Giles, Michael E. Teachman, Jeffrey W. Yeo, Chuen Shan Simon Ki

Patent number: 6983211Abstract: A method and arrangement are disclosed for attaching one or more electrical bayonet-type blades to a circuit board with the bayonets being used to receive voltage and current signals from the electric circuit of an electrical meter. The arrangement includes a circuit board with at least one opening adapted to receive one blade. In addition, a sensor is coupled with the electric circuit to sense at least one electrical parameter from the circuit and generating a corresponding analog signal. A solder pad disposed on at least one surface of board surrounds the opening. Solder is applied around the electrically conducting bayonet on one surface of the circuit board and around the electrically conducting bayonet of the surface of the circuit board opposite to the solder pad.Type: GrantFiled: December 4, 2002Date of Patent: January 3, 2006Assignee: Power Measurement, Ltd.Inventors: I. Ross Macfarlene, Peter C. Cowan, David W. Giles, Markus F. Hirschbold, Rene T. Jonker

Patent number: 6825776Abstract: A revenue meter includes electronics for measuring the delivery of electrical energy from an energy supplier to a consumer through an electric circuit. An interface link connects to the revenue meter. An I/O and communications device connects through the interface link to the revenue meter. The I/O and communications device may also connect to a second electric circuit. The I/O and communications device uses a serial interface to communicate with the revenue meter. The I/O and communications device provides one or more of analog inputs and outputs, digital inputs and outputs, and communications ports.Type: GrantFiled: August 9, 1999Date of Patent: November 30, 2004Assignee: Power Measurement Ltd.Inventors: Simon H.

Patent number: 6000034Abstract: A security system for programmable revenue class electricity meters. Each programmable revenue class electricity meter includes a metering portion or stage that couples to a power line. The metering portion is responsive to and senses the electricity in the power line and provides a digital output. The programmable revenue class electricity meter includes a processor that runs programming that records, calculates, and/or stores data relating to the electricity sensed by the metering portion. In particular, the programming records, calculates, and/or stores revenue-related data that can be used for calculating charges for the electricity. The programming can be changed by authorized persons to modify the types of data that can be measured, calculated, recorded, displayed, communicated, and/or stored for any desired purpose and in particular for revenue-related purposes. Modification of the programming and access to information is limited to authorized persons by means of the security system.Type: GrantFiled: May 6, 1997Date of Patent: December 7, 1999Assignee: Power Measurement Ltd.Inventors: Simon Lightbody, David W.
