Overhead Power Transmission Lines Economic Efficiency Diagnostic Assessment

2018 XIV International Scientific-Technical Conference on Actual Problems of Electronics Instrument Engineering (APEIE), 2018
The overhead power transmission line diagnostics is a part of a current production operation of electric grid company. The list of diagnostic types has to be developed on the basis of technical and economic factors. The solution of technical tasks is primary, and the additional diagnostic types should be used if the cost advantages are available.

On Real-Time Detection of Line Sags in Overhead Power Grids Using an IoT-Based Monitoring System: Theoretical Basis, System Implementation, and Long-Term Field Verification

IEEE Internet of Things Journal, 2022
For overhead power grids, unexpected serious line sagging of extra-high voltage transmission lines would easily lead to major blackouts. Different direct and indirect sag measuring methods have been proposed, but they all have their own limitations.

Design and implementation of power line sensornet for overhead transmission lines

2009 IEEE Power & Energy Society General Meeting, 2009
The task of monitoring asset status and optimizing asset utilization for the power grid, given millions of assets and hundreds of thousands of miles of power lines distributed over millions of square miles, seems costly, if not impossible. Given the traditionally high cost of sensing and communications, the current grid has minimal ‘smarts’ with much ...

Computerized design of overhead transmission power lines

Proceedings of ESMO '93. IEEE 6th International Conference on Transmission and Distribution Construction and Live-Line Maintenance, 2002
The conventional design of overhead transmission power lines by manual survey, mapping and design techniques, involve costly and time consuming activities. Massive documentation is accumulated during the preliminary studies of terrain, alternative routes selection, power-line hardware configuration, cost-effectiveness-performance optimization, and more.

Comparative analysis of overhead power transmission lines based on loadability characteristics

2011 International Conference on Clean Electrical Power (ICCEP), 2011
The loadability curves of different types of overhead transmission lines are computed and compared in this paper, for line length up to 500 km. The considered solutions are: traditional three-phase single and double circuit ac lines, four-phase ac lines, monopolar and bipolar HVDC lines and combined ac-dc lines.

Experience of CLP power transmission overhead lines operation and maintenance

7th IET International Conference on Advances in Power System Control, Operation and Management (APSCOM 2006), 2006
The performance of CLP Power (CLPP) transmission overhead lines (OHL) is affected by geological, meteorological, environmental, technical and social factors. Since the commission of the 400 kV transmission OHL system in 1981, lightning and insulator contamination have been the major causes of system faults in CLPP.

Electronic airborne inspection method for overhead transmission power-lines

Proceedings of ESMO '93. IEEE 6th International Conference on Transmission and Distribution Construction and Live-Line Maintenance, 2002
Overhead transmission power lines are the most cost effective and frequently used carriers for electric energy. Exposure to environment accelerates deterioration, originating small failures, some of them, if not timely detected and repaired, to become serious problems with time.
