Five Surprises Discovered With Megahertz Sampling and Traveling-Wave Data Analysis

Date held: January 16, 2019
Duration: 75 min

High-frequency traveling-wave technology has become mainstream in power systems, bringing with it an unprecedented level of highly accurate signal details. High-frequency traveling-wave transients made visible by this technology have proven their practical value for ultra-high-speed protection and accurate fault locating.

This webinar shows and explains some of the more surprising, lesser-known, and strange-looking waveforms captured while monitoring high-voltage transmission lines. The webinar also explains the limitations and distortion introduced by conventional secondary wiring systems, helping engineers interpret detailed event data captured by the latest generation of protective relays and digital fault-recording systems.

We focus on monitoring primary apparatus health and identifying high-voltage system sources generating the traveling-wave transients. To analyze the data, we use Clarke components, Bewley diagrams, and spectral analysis methods.
