Reactive compensation of overhead AC transmission lines using underground power cables
2015 IEEE Power & Energy Society General Meeting, 2015Overhead (OH) transmission lines when loaded always consume reactive power. An underground (UG) power cable on the other hand is in itself a huge capacitor and therefore a source of reactive power. This paper highlights the use of UG power cables in conjunction with overhead lines, where the reactive power requirement of overhead line is compensated by

Vibration Failure and Restoration of Overhead Power Transmission Line
The Shock and Vibration Digest, 1995Presented Is a review of a case of vibration failure of the tension Insulator string of a 110 kV, overhead line due to transmitted aeolian vibration. The restoration of the line after replacement of failed Insulators and added damping Is detailed.

Interaction of Structural Elements in the Overhead Transmission Power Line
Zhilishchnoe Stroitel'stvoThe analysis of the changes of tensile forces in conductors and earth wires is performed during their breakage and impact on the towers of overhead power line with a voltage of 330 kV. Based on the results, a mathematical model of a unified cable-stayed rod system consisting of steel towers, conductors and earth wires and insulating elements has been ...
