Tapping IED data to find transmission faults

Abstract

This article describes a data analysis tool that allows electric utility personnel to automatically and accurately compute the location of faults on power transmission lines and analyze fault data without cumbersome manual data retrieval and calculation procedures. When a fault is detected anywhere on the power network, an operator needs only to identify the faulted line, and the data analysis tool will compute the location of the fault as accurately as possible using the information available.
