Faultpoint® Add-in Module for PQView®

Enable Fault Analysis & Location Functionality

As an included function of the PQView® software, FaultPoint® combines three functions: fault identification from waveform samples, estimation of impedance-to-fault from the waveforms and display of the estimated fault location using interactive one-line diagrams and maps.

“The recent addition of [Faultpoint’s] advanced fault-location capability has significantly increased the value of these systems, reducing the time required to locate feeder faults at Con Edison by more than one hour.”
