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. Jonker, Piotr B. Przydatek, Colin N. Gunn, Michael E. Teachman, Constantine A. Antoniou

Publication number: 20030014678Abstract: A time synchronization device and method for synchronizing an internal clock of the power monitor to a periodically stable frequency. Cycles of the periodically stable frequency are counted after each elapse of a predetermined time period. The elapse of the predetermined time period defines a present window and a previous window. A counting error and a change in counting error are calculated, wherein the change in counting error is the difference of a counting error calculated for the present window and a counting error calculated for the previous window. The present method detects when a change in counting error is within a predetermined range. When the counting error is within the predetermined range, the internal clock of the power monitor is adjusted to the line frequency according to the counting error calculated for the present window.Type: ApplicationFiled: August 9, 1999Publication date: January 16, 2003Inventors: H.
