Detecting Loose Neutrals: Enhanced Visualization with ProVision Graph Templates
This white paper introduces a new graph template for ProVision software that enhances the detection and analysis of loose or open neutral conditions in single-phase residential electrical services. By plotting one-cycle minimum and maximum voltages from two channels, the template visually highlights the characteristic voltage separation that signals a loose neutral event. The approach enables more granular identification of both sustained and intermittent neutral issues, even when standard reports may not trigger, providing a continuous and detailed view of voltage behavior during recording sessions.
Key topics include:
- Characteristics of Loose Neutral
- Graphing Loose Neutrals with ProVision
- Analysis of Example Recordings
Why utilities should care:
Early identification of loose or open neutrals reduces equipment damage, fire risk, and customer complaints. Enhanced visualization tools enable faster, more accurate troubleshooting and support proactive maintenance, improving reliability and safety of electrical distribution.
