RT-TLMS Applications
Promethean Devices’ RT-TLMS serves stakeholders in Transmission Planning, Transmission Operations, Transmission Reliability, T & D Asset Management, and in Bulk Power Delivery.
Actual and putative applications of RT-TLMS data are as follows:
- Measure Phase Conductor Clearance
- Anchor/verify survey data and PLS-CADD models
- Reveal affects of thermal history
- Monitor Conductor Temperature
- Detect and track high Tconductor events and excursions
- Track time-at-temperature
- Estimate actual and aggregate loss of strength
- Estimate remaining operational lifetime
- Capture All Phase Currents w/ High Accuracy
- Inexpensively monitor transmission circuit taps
- Estimate Real-time Dynamic Ampacity (Thermal Rating)
- Reveal and Quantify Hidden Transmission Capacity
- Reveal actual thermal capacity
- Quantify actual (latent) thermal capacity
- Optimize Power Transfer Capability (ATC/TTC)
- Establish real-time dynamic line rating methods
- Verify, or increase path ATC, or inform ATC calculations
- Verify, or increase network TTC, or inform TTC calculations
- Improve Operational Reliability
- Ensure Operational Compliance
- Detect and track impending or imminent clearance violations
- Enhance and Inform T & D Asset Management Methods and Practices
- Increase Static Rating w/ High Accuracy and Confidence
- Establish Quasi-static Rating(s)
- Intelligently Defer Some Transmission Asset Upgrades
