摘要
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.
