Analysis of Induced Voltage on Pipeline Located Close to Parallel Distribution System

open access: yesEnergies, 2021
Gas and oil pipelines are widely used to supply customers. They are often laid in parallel with high voltage power lines, sharing right of way. When the pipeline is located near overhead high-voltage power, corrosion caused by induced voltages from AC ...

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 ...
