Record, Diagnose and Troubleshoot Oscillatory Transients

This white paper focuses on the identification, analysis, and mitigation of oscillatory transients in electrical networks using PQ Canvass and Seeker PQ recorders. Oscillatory transients result from switching operations, lightning strikes, or impulsive noise, causing electrical resonances. The document provides detailed steps for waveform data collection, including waveshape triggering based on voltage total harmonic distortion. It explains how to find and isolate resonances in captured data, estimate ring frequencies, and employ harmonic magnitude plots for verification.
