Simplifying ITIC/CBEMA Voltage Event Analysis with RMS Stripcharts
This white paper presents a practical approach for identifying and interpreting ITIC/CBEMA voltage events using standard RMS voltage stripcharts. By overlaying ITIC thresholds on stripchart data, the method enables easier correlation of voltage sags and swells with load changes, especially in residential settings, and provides actionable insights even for power quality recorders lacking native ITIC event capture.
Key topics include:
- Introduction to ITIC/CBEMA Curves
- Stripchart Data Collection and Interpretation
- Mapping ITIC Events on RMS Stripcharts
- Thresholds and Event Classification
- Practical Examples and Annotations
Why utilities should care:
Understanding how to visualize ITIC/CBEMA events on RMS stripcharts enables clearer communication of voltage quality, supports compliance verification, and enhances troubleshooting, especially when advanced event capture is unavailable or when engaging non-technical audiences.
