  • Apparatus and method for measuring and reporting the reliability of a power distribution system
    Patent number: 6671654
    Abstract: An intelligent electronic device for measuring various power parameters from a electrical power distribution system is disclosed. The device is capable of measuring and reporting the reliability of the electrical power distribution system as the number of consecutive 9's digits appearing in the computed percentage of system downtime versus system uptime. Depending on the level of reliability required, the computation of the percentage may be altered to increase or decrease resolution.
    Type: Grant
    Filed: November 28, 2000
    Date of Patent: December 30, 2003
    Assignee: Power Measurement Ltd.
    Inventors: J. Bradford Forth, Michael E. Teachman, Jeffrey W. Yeo
  • Apparatus and method for measuring and reporting the reliability of a power distribution system with improved accuracy
    Patent number: 6611773
    Abstract: An intelligent electronic device for measuring various power parameters from a electrical power distribution system is disclosed. The device is capable of measuring and reporting the reliability of the electrical power distribution system as the number of consecutive 9's digits appearing in the computed percentage of system downtime versus system uptime. The number of 9's is computed in a manner which does not incur inaccuracies at high resolutions due to digital floating point mathematical computation methods.
