Vegetation Height Estimation Near Power transmission poles Via satellite Stereo Images using 3D Depth Estimation Algorithms [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2015 Monitoring vegetation encroachment under overhead high voltage power line is a challenging problem for electricity distribution companies. Absence of proper monitoring could result in damage to the power lines and consequently cause blackout.

Reliability Assessment of Transmission Poles
European Journal of Engineering and Technology Research, 2022 The structural reliability of round wood and fiber-reinforced polymer (FRP) composite transmission poles is investigated. Numerical reliabilities at ultimate loads for 20 poles are computed and compared. The main inference from this limited study is that FRP poles showed higher structural reliability than wood poles; the average reliability index of ...

Multi‐pole voltage source converter HVDC transmission systems [PDF]
IET Generation, Transmission & Distribution, 2016 This study connects several modular multilevel converters to form multi‐pole voltage source converter high‐voltage dc (VSC‐HVDC) links which are suited for bulk power evacuation, with increased resiliency to ac and dc network faults. The proposed arrangements resemble symmetrical and asymmetrical HVDC links that can be used for bulk power transfer over

Compact dual-mode triple-band bandpass filters using three pairs of degenerate modes in a ring resonator [PDF]
, 2011 In this paper, a class of triple-band bandpass filters with two transmission poles in each passband is proposed using three pairs of degenerate modes in a ring resonator. In order to provide a physical insight into the resonance movements, the equivalent
