Achieve High-Resolution Power Quality Insights with the Significant Change Graph

This white paper explores the Significant Change graph, a triggered event-based visualization that captures voltage changes with one-second resolution. It demonstrates how this method augments or replaces traditional RMS stripcharts, especially in long recordings or when memory constraints limit data retention, providing detailed, actionable insights into power quality events.

Key topics include:

- Significant Change Record Overview
- Significant Change Graph
- Using the Graph

Why utilities should care:
Enhanced event detection and data compression enable precise monitoring of voltage fluctuations, even in extended recordings or limited-memory scenarios. This approach supports better root-cause analysis, regulatory compliance, and clear communication with technical and non-technical stakeholders.
