Analysis of Overhead Transmission Line Inspection

Title: Aerial Surveillance System for Overhead Power Line Inspection

Electrical companies routinely inspect their overhead lines by helicopter. Current detailed aerial inspection approach uses trained inspectors who fly aboard helicopters to inspect the lines with binoculars and cameras, while recording the data in a logbook. The procedure is performed while the helicopter hovers over and around power lines and structures, creating an element of danger for the p...

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...

High Frequency Analysis of Single Overhead Line Terminated to Grounded Arrester

In this paper, intelligent models based on fuzzy inference are proposed to analyze single overhead line terminated to arrester. This paper consists of two parts. The first one is modeling overhead line and the second one is related to modeling grounding system. In each part, the behavior of the problem is first represented as simple and unchanged membership functions. After then, effects of par...

A Novel Method of Autonomous Inspection for Transmission Line based on Cable Inspection Robot LiDAR Data

With the growth of the national economy, there is increasing demand for electricity, which forces transmission line corridors to become structurally complicated and extend to complex environments (e.g., mountains, forests). It is a great challenge to inspect transmission line in these regions. To address these difficulties, a novel method of autonomous inspection for transmission line is propos...
