Dynamic Cable Rating
Maximise grid performance with real-time, intelligent cable monitoring.
Bandweaver’s Real-Time Thermal Rating (RTTR) system combines a dynamic cable rating algorithm with real-time thermal data from Distributed Temperature Sensing (DTS) and live current load data. This integration provides operators with accurate, dynamic cable ratings — enabling higher utilisation, improved reliability, and safer operation compared to fixed static ratings.
BENEFITS
Increased Capacity
Unlock hidden headroom by safely running cables closer to their true limits
Enhanced Reliability
Identifies abnormal heating, cable vibration, mechanical stress, or early-stage corrosion.
Deferred Investment
Monitors the entire length of an asset with no blind spots.
Continuous Insight
Prevents costly failures by addressing issues before they escalate.
Better Asset Management
Extend service life and reduce operational risk with proactive monitoring.
Regulatory Compliance
Built on IEC 60287, IEC 60853 and CIGRÉ guidelines, ensuring global best practice.
TYPES OF SYSTEMS
Underground Transmission Cables
DCR uses DTS data to create a complete thermal profile of long high-voltage circuits. Operators can dynamically adjust ratings in response to soil conditions, backfill, and load changes, improving grid security.
- Increased power transfer capability without compromising safety
- Early warning of abnormal conditions such as soil drying or backfill degradation
- Reduced outage risk and improved grid stability
Underground Distribution Cables
Urban and medium-voltage networks face fluctuating demand and congested duct environments. DCR enables utilities to avoid bottlenecks and defer costly upgrades while maintaining safety and reliability.
- Optimised network utilisation and deferred reinforcement costs
- Improved detection of localised hotspots (e.g. joints, congested ducts)
- Enhanced reliability for critical customers and urban networks
Subsea Cables
Export and inter-array cables for offshore wind and marine interconnectors face complex seabed conditions. DCR provides continuous, real-time thermal insight to maximise transmission capacity and reduce operational risk.
- Maximised output from offshore wind and subsea corridors
- Long-term protection of hard-to-access assets
- Reduced risk of unplanned outages in critical power links
Interconnectors
Cross-border links are critical national assets. DCR ensures safe maximum utilisation of these multi-billion-dollar projects, delivering higher transfer capacity while maintaining thermal integrity.
- Maximise utilisation of multi-billion-dollar infrastructure
- Improve resilience of cross-border power flows
- Extend asset life with proactive condition monitoring
