Several studies have been conducted to quantify the electromagnetic fields generated by power lines in order to evaluate the risk of these fields on human and animals health. In this paper, extremely low frequency electric and magnetic fields generated by a complex system contains six parallel high voltage lines are calculated using COMSOL — MULTI PHYSICS software. This study is used to analyze the...
Lightning fascinates and frightens us. The considerable damage it causes to property and its unfortunate victims plainly demonstrate that the imaginary is based on a phenomenon that is very real and can be fairly well explained, but cannot be combated. Lightning is one of those natural events which catches people's imagination with its obvious violence and the destructive power attributed to it. Only...
There are numerous practical problems for which we need to know the spatial distribution of artificialy created electromagnetic fields, generated by the human due to advances in technology and widespread use of electrical devices. Low frequency electromagnetic fields around power transmission and distribution networks are time-varying quasistatic electromagnetic fields that have a conservative (non...
The objective of this paper is to contribute with the researches on the mapping of the electromagnetic fields of transmission lines using the Charge Simulation Method and MATLAB to develop a software that is capable of measure the electromagnetic fields of transmission lines. The software has several different analyses for the electromagnetic fields, which include the electromagnetic graphs, the 3-D...
This paper presents results of measurements and computations of the electric and magnetic fields of complex busbars, transformers and transmission line structures at transformer station 400/110 kV. The fundamental sources of low frequency electromagnetic fields in the transformer station are the primary elements of the 400 and 110 kV open substations and associated overhead lines. Due to the complexity...
Knowing electromagnetic field inside and in the neighborhood of any power electric cable is very important because of the cable influence on its vicinity. This paper shows the determination of a 3-phase cable system electromagnetic field, applying the COMSOL multiphysics computer program. Two components of electric field strength vector, potential electric field and induced electric field, are calculated...
