Pinpointing the Source: Distinguishing Transmission and Distribution Voltage Events with Strategic Monitoring
This white paper demonstrates how deploying Boomerang voltage monitors and Canvass data analysis across a distribution system enables clear identification of voltage events originating from transmission lines versus those caused by local distribution or customer loads. By overlaying voltage traces from multiple locations, utilities can distinguish the root cause of voltage sags and swells, assess regulator responses, and optimize monitor placement for comprehensive system insight.
Key topics include:
- Understanding Superposition in Electrical Networks
- Spotting Transmission Events
- Checking Regulator Responses
- Boomerang Placement Strategies
- Case Study: Load-Induced Voltage Sags
Why utilities should care:
Strategic voltage monitoring enables rapid identification of event origins, optimizes regulator settings, and supports compliance with voltage standards. This approach enhances system reliability, reduces unnecessary equipment wear, and improves response to customer power quality issues.
