UNDERGROUND SOLUTIONS MRDC (Monitoring – Rating – Diagnostics – Controls) Product Overview Reduce capital and operating costs and exploit a system’s excess reserve capacity by up-rating load levels. USi has a proven solution: the UPRATE™ dynamic rating system – a knowledge-based result incorporating years of staff experience and a range of monitoring equipment for both overhead and underground cable systems. UPRATE™ thermal monitoring and ratings system use real-time temperature measurements and thermal models to provide dynamic ratings. It dramatically increases the ratings over “book” value for both overhead and underground cables. Transmission capacity is not only increased, but made safer because the UPRATE™ system computes capacity based on actual cable component temperature and environmental conditions, rather than assumptions. System monitoring, ratings, and diagnostics for overhead and underground systems and cathodic instrumentation can help improve the capacity, efficiency and reliability of power delivery systems.
