Unlike traditional magnitude-based triggers, the THD-based approach effectively captures subtle waveform shape changes - such as those caused by capacitor bank switching - without generating excessive false triggers. The paper also details new cross-triggering capabilities and enhanced reporting features, providing a comprehensive solution for accurate power quality event detection. **Key topics include:** - Overview of Traditional Trigger Mechanisms - Limitations of Existing Approaches - Introduction to THD-Based Triggering - Implementation in Revolution and Vision Devices - Cross-Triggering and Enhanced Reporting - Case Studies and Example Captures **Why utilities should care:** Accurately detecting waveform shape changes enables better identification of power quality disturbances that may not affect RMS voltage, reducing false positives and improving event analysis. Enhanced reporting and flexible triggers support more reliable grid monitoring and diagnostics.
