Tension and Ampacity Monitoring System for Overhead Lines
(IEEE, 2013-01-01)
Real time monitoring allows the determination of the line state and the calculation of the actual rating value. The real time monitoring systems measure sag, conductor tension, conductor temperature or weather related ...
Influence of the conductor temperature error on the overhead line ampacity monitoring systems
(The Institution of Engineering and Technology, 2011-04)
Many real time overhead line ampacity monitoring systems are based on the calculation of the wind speed. The wind speed is obtained from the conductor temperature. The conductor temperature can be measured directly or it ...
Forecast Ratio and Security Analysis of Rating Forecasting Methods in an Overhead Line
(The Institution of Engineering and Technology, 2017-01-26)
The actual line rating in overhead lines varies with weather conditions. When a utility defines a rating value for the operation of the line, it takes into account both the security and the forecast ratio. The defined ...
