What is Data Mining for Substation Relays about?

This document summarizes a paper that analyzes fault data recorded by digital relays in several substations to classify fault types and verify relay settings using data mining techniques. It describes the format of the data recorded by the relays, including date, time, firmware information, currents and voltages, overcurrent elements, output/input contacts, event type, location, shots, targets, and settings. It then discusses using decision trees to classify faults based on observing pre-fault and fault cur
