چکیده
The meshless element-free Galerkin method (EFGM) is used to solve partial differential equations responsible for obtaining the electromagnetic fields generated by a transmission line. For this purpose, 2D model based in real line constructed and simulated. results obtained EFGM have good accuracy they are compared against analytical solution Finite Element Method order verify effectiveness, advantages disadvantages of method.

Emissions of electromagnetic fields caused by sagged overhead power lines
Nowadays people became aware of the overhead lines and their emissions of electromagnetic fields. This work presents a method for calculation of the electric field strength and magnetic field density caused by the overhead power lines at the ground level. The method considers the conductor sagging. It is shown that the sagged conductors can be replaced with the properly placed straight conducto...

Nowadays, people are highly concerned about the effects of high voltage transmission lines on their health. Probable risk for leukemia, breast cancer, neuropsychological disorders and reproductive outcomes has been reported due to this exposure. In this study, several measurements around different areas such as overhead transmission lines, GIS compartments and some appliances have been conducte...
متن کاملPower transmission capacity upgrade of overhead lines
Electric power consumption, has been increasing uninterruptedly, being this increase specially accelerated in the last years. New power generators are been built, the installed power increases each year, thus it is necessary a way to transmit the bulk energy. Nowadays electric lines are saturated, they are reaching critical values of ampacity and sag. Therefore building new lines is necessary t...
متن کاملAccurate Electromagnetic Transient Simulations of HVDC Cables and Overhead Transmission Lines
This paper introduces three different procedures for improvements in the accuracy at very low frequencies of time domain simulation models for overhead lines and underground cables. In the first two methods, a suitable modification is introduced to the functional form of the rational function approximated in the curve fitting procedure for the phasedomain model, such that the model is perfectly...
متن کاملCriterion for selecting the shape functions in electromagnetic meshless methods
The root of this study, comes from the lack of regularity where exists in shape function selection in meshless methods. Up to now, shape functions in meshless methods were being established by basis functions. In other words, there was no predictable rule by which the shape functions be predetermined, without any need to basis functions. In presented approach, the authors are going to establish...
