Magnetic Field Lines from Overhead Conductors.
(Phase A = Red, Phase B = Green, Phase C = Blue).
Sensors under each phase detect the magnetic field and the RT-TLMS determines the phase current.
Once calibrated, the RT-TLMS reports real time current, conductor sag, temperature and ampacity.
This innovative dynamic rating system for overhead transmission lines is now available for commercial applications.
Developed with assistance from the US Department of Energy and utilizing the AC magnetic fields under overhead transmission lines, Promethean Devices now offers our RT-TLMS for use where transmission line loading and congestion is a concern.
The RT-TLMS Provides the following information:
- Current
- Conductor Sag or Clerance
- Conductor Temperature
- Ampacity
PROTECT YOUR TRANSMISSION LINE INVESTMENT
- Safely increase loading of existing transmission lines
- Improve control, operational reliability and power transfer capability
- Relieve congestion and increase asset utilization
- Defer the costs of upgrades and new construction
Real Time Ampacity & Thermal Capacity showing actual
Transmission Capacity more than 15% above the Static Rating
for more than 50% of the month
