ADULT CANCERS NEAR HIGH-VOLTAGE OVERHEAD POWER LINES

open access: yesISEE Conference Abstracts, 2013
Extremely low-frequency magnetic fields are designated as possibly carcinogenic in humans, based on an epidemiologic association with childhood leukemia. Evidence for associations with adult cancers is weaker and inconsistent.We conducted a case-control study to investigate risks of adult cancers in relation to distance and extremely low-frequency ...

Impact of Conductor Temperature Time–Space Variation on the Power System Operational State

open access: yesEnergies, 2018
The conductor temperature of an overhead transmission line varies with time and space, which has an important impact on the system operation. In this paper, the conductor temperature is solved iteratively by the CIGRE heat balance equation.

Method for control the mechanical parameters of overhead power lines based on improved inclinometry

open access: yesИзвестия высших учебных заведений: Проблемы энергетики, 2019
Structural elements of overhead power transmission lines are experiencing both horizontal and vertical loads. Wires and cables are elements of the overhead power line, on which changes in mechanical loads are observed to a greater degree. This occurs due

Induced losses in linear equipment buried near an overhead power line

open access: yes, 2012
This work focused on the influence of an overhead power line on buried linear equipment (cable, pipeline). Its aim was to analyze the volumetric losses in buried linear equipment as a function of the distance from an overhead power line. The computations

Overhead electricity line connector tester [PDF]

open access: yes, 2003
Assessment of the condition of connectors in the overhead electricity network has traditionally relied on the heat dissipation or voltage drop from existing load current (50Hz) as a measurable parameter to differentiate between satisfactory and failing ...
