Ensuring Reliable Traffic Operations Through Effective Power Quality Management
This white paper explores the complex power architectures within modern traffic signal cabinets, focusing on the impact of power quality (PQ) issues and the role of uninterruptible power supplies (UPS). It highlights how improper UPS operation can worsen PQ problems, leading to intersection failures, and provides best practices for monitoring and troubleshooting to distinguish between utility and cabinet-originated issues.
Key topics include:
- Cabinet Architecture
- UPS Architecture
- Monitoring Recommendations
Why utilities should care:
Understanding the interplay between utility supply and cabinet internals is crucial for minimizing outages, reducing maintenance costs, and ensuring public safety at intersections. Accurate PQ monitoring and UPS configuration can prevent unnecessary service calls and improve operational reliability.
