Abstract
In a previous study on electric fields near 400 kV transmission lines it was
noticed that the differences in calculations and measurements were caused
by trees dampening the electric field. This caused the need for further
investigation and dampening measurements. The aim of this study is to
model single trees and forest, in the calculation of electric fields using the
Finite Element Method (FEM).
International Commission on Non-Ionizing Radiation Protection
(ICNIRP) has published guidelines for public and occupational exposure to
50 Hz electric fields caused by power transmission lines. They are 5 kV/m
and 10 kV/m, respectively. There are some spans, where guideline for public
exposure may be exceeded. Thus it is importan
