3D COMPUTATION OF THE OVERHEAD POWER LINES ELECTRIC FIELD

open access: yesProgress In Electromagnetics Research M, 2017
In this paper, a 3D quasistatic numerical algorithm for computation of the electric field produced by overhead power lines is presented. The real catenary form of the overhead power line phase conductors and shield wires is taken into account with an arbitrary number of straight thin-wire cylindrical segments of active and passive conductors.

An Optimized Coordination Strategy between Line Main Protection and Hybrid DC Breakers for VSC-Based DC Grids Using Overhead Transmission Lines

open access: yesEnergies, 2019
Compared with alternating current (AC) power grids, the voltage-sourced converter (VSC)-based direct current (DC) grid is a system characterized by “low damping„, as a result, once there is a short-circuit fault on the DC transmission line ...

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 ...
