Techniques for On-Line Diagnosis of Stator Shorted Turns in Induction Motors
(Taylor & Francis, 2006-01)
In low voltage induction motors, the first indication of a stator fault is the appearance of an inter-turn short circuit. For this reason, several attempts to diagnose reliably these short circuits have been made. Although ...
Aspects to take into account in the application of mechanical calculation to high temperature low sag conductors
(The Institution of Engineering and Technology, 2010-05)
Reconductoring with high temperature low sag (HTLS) conductors is an alternative to the traditional uprating methods. The obtained rating increase depends on the mechanical and thermal behaviour of the conductor. In this ...
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 ...
Flexible Strain-Tension Calculation Method for Gap-type Overhead Conductors
(IEEE, 2009-07)
Commercially available sag-tension programs give good results for most practical applications. However, they have some limitations concerning gap-type conductors. A separate aluminum and core creep calculation is needed ...
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 ...
