Probabilistic Mechanical Design of Overhead Transmission Line

Mechanical Design of Overhead Lines

8.17 Some Mechanical Principles Introduction Electric power can be transmitted or dis tributed either by means of underground cables or by overhead lines. The underground* cables are rarely used for power transmission due to two main reasons. Firstly, power is generally transmitted over long distances to load centres. Obviously, the installation costs for underground transmission will be very h...

Accurate Fault Classification of Transmission Line Using Wavelet Transform and Probabilistic Neural Network

Fault classification in distance protection of transmission lines, with considering the wide variation in the fault operating conditions, has been very challenging task. This paper presents a probabilistic neural network (PNN) and new feature selection technique for fault classification in transmission lines. Initially, wavelet transform is used for feature extraction from half cycle of post-fa...

Mitigation of Magnetic Field under Double-Circuit Overhead Transmission Line

This paper studies the effect of various mitigation loop configurations namely: single horizontal mitigation loop (two conductors), two separate horizontal mitigation loops (four conductors) and single vertical mitigation loop (two conductors), on the magnetic field produced by 220 kV double-circuit overhead transmission line. Also, in this paper a further reduction in the magnetic field is ach...
