The invention relates to an automated process for monitoring and evaluating the integrity of an active line and/or neutral line for a polyphase site. The process uses measurements obtained at the site to estimate the voltage and impedance of the neutral line. These estimates are compared with established operating zones for the site to evaluate the condition of the active and/or neutral line. An electrical utility meter installed at the site captures instantaneous usage measurements (typically the voltage and current for each phase of an electrical supply). The measurements are transmitted to an evaluation module that derives active and/or neutral line performance characteristics for the site. |
