Unlocking High-Resolution Power Quality Insights Through Optimized Waveform Capture Triggering
This white paper explores the principles and practical configuration of waveform capture triggers for power quality analysis. It details threshold, periodic, and cross-triggering methods, and provides scenario-based guidance for optimizing settings to maximize memory use, minimize false captures, and ensure critical events are recorded. Real-world examples illustrate best practices for motor starts, voltage sags, waveshape events, and harmonic studies, empowering users to tailor monitoring for specific investigative needs.
Key topics include:
- Introduction to Waveform Capture Triggering
- Types of Triggers: Threshold, Periodic, and Cross-Triggering
- Configuring Threshold Triggers
- Periodic and Cross-Trigger Mechanisms
- Memory Management: Pre/Post Cycles, Sampling, and Channels
- Overwrite and Storage Strategies
- Scenario-Based Settings: Motor Starts, Voltage Sags, Waveshape Events, Harmonic Studies
Why utilities should care:
Effective configuration of waveform capture triggers enables precise event detection, efficient memory use, and targeted power quality analysis. This enhances troubleshooting, supports compliance, and ensures critical disturbances are documented for informed operational decisions.
