“…The transmission of alternating current electrical power [3], generates associated effects such as losses due to the corona effect, audible noise, and radio and television interference. Transmission lines are considered one of the principal sources of electric and magnetic fields [4]- [7]. The intensity of the fields emitted by these lines depends mainly on the transmitted current and their voltages.…”

“…In the easement zone or the right-of-way permit along the transmission line, the electric and magnetic field values must be lower than the reference levels specified above. If the rates of the fields are above the permissible limits, the design should be revised [4], [24].…”

“…Through a documentary review on electric and magnetic fields in transmission lines, multiple works associated with software development with an interface that eases the learning process, or the accompaniment as a work tool, were identified. Thus, in study [4], the authors analyze the design of a 765 kV line in Gujarat, India. In this study, they determine the field profiles employing an interface developed in the MATLAB Guide application.…”

<span lang="EN-US">There is an interest in the biological effects of exposure to low-frequency electromagnetic fields issued by transmission lines on animals and humans. The fields generated by the lines are relevant for the design and operation of power systems. The study of the electric and magnetic fields in the transmission networks implemented commercial simulators bases on the finite element method. These commercial simulators are characterized by accuracy and high hardware and software requirements. This work presents CEM-LT, a tool that accurately precisely the electric and magnetic field in the transmission lines, with simple and intuitive handling and low processing times, making it ideal for being implemented together with optimization methods. The electric and magnetic field in the servant area for two case studies is analyzed to evaluate the accuracy and processing times. The level of accuracy is characterized by comparing the results with COMSOL obtaining errors of less than 2.4%. The case study with the highest computational requirement achieved a processing time of 3,027 seconds.</span>

“…Bu nedenle, iletim hattının çevresindeki güvenli alanın sadece atlama mesafesi dikkate alınarak değil, elektrik ve manyetik alan analizleri yapılarak belirlenmesi önem arz etmektedir. Bu konuda yapılan birçok benzetim ve deneysel çalışma mevcut olmasına karşın, farklı geometrilerde direkler kullanılması ve iletim gerilim seviyelerinin birbirlerinden farklı olması nedenleriyle hala çalışmaya ihtiyaç duyulmaktadır [2], [16], [20]- [25]. Teknik sorunlar ve/veya güvenlik nedenleriyle hatların yer değiştirilmesi (deplase) durumunda da analizlerin tekrarlanması gerekmektedir.…”

Enerji iletim hatlarında incelenmesi gereken önemli konulardan biri de hatların meydana getirdiği elektrik alanın, çevresindeki yaşam alanları üzerindeki etkileridir. Yüksek gerilim nedeniyle oluşan elektrik alanın insan sağlığını etkilemesi ve olası atlama risklerinin engellenmesi için iletim hatları ile yaşam alanları arasında yeterli açıklıkların bırakılması gerekmektedir. Günümüzde, hızla artan nüfus ve genişleyen yerleşim alanları nedeniyle, havai iletim hatlarının yaşam alanları üzerinden geçtiği veya bu bölgelere yaklaştığı durumlarla karşılaşılabilmektedir. Bu nedenle, özellikle yaşam alanları içerisinde bulunan iletim hatlarının neden olduğu elektrik alan değerlerinin hesaplanması, ölçülmesi ve insan sağlığı bakımından kritik yaklaşma mesafelerinin belirlenmesi oldukça önemlidir. Bu çalışmada, çift devre 154 kV ve tek devre 400 kV'luk iki iletim hattından oluşan enerji iletim sisteminin ayrı güzergâhlarda olması ve deplase edilerek tek devre üzerinde toplanması durumları dikkate alınarak elektrik alan analizleri gerçekleştirilmiştir. Modelleme çalışması, sonlu elemanlar yöntemi kullanan Comsol Multiphysics yazılımı ile gerçekleştirilmiştir. Elde edilen sonuçlar yardımıyla, uluslararası kriterlere uygun olarak güvenli yaklaşma mesafeleri belirlenmiştir. One of the important topics to be examined in the energy transmission lines is the effects of the electric field generated by the lines on the public areas around it. It is essential to leave enough spaces between the transmission lines and the living areas in order to prevent the risks of potential discharges and the electric field caused by high voltage. Today, due to the rapidly growing population and expanding residential areas, the situations where overhead transmission lines pass through or get close to living spaces can be encountered. Therefore, it is very important to calculate and measure the electrical field values caused by the transmission lines in the living areas and to determine the critical safe right of way distances in terms of human health. In this study, electric field analysis are performed by taking into account two lines, double circuit 154 kV and single circuit 400 kV, for separate routes and displaced on single tower. Modeling study is performed by Comsol Multiphysics software based on finite element method. By the help of the results obtained, safe right of way distances are determined in accordance with international criteria.

“…In recent years, several publications have been made to calculate the electric and magnetic fields created by power transmission lines. Most assume that the power lines are horizontal straight parallel to a flat ground, and the sag due to the power line weight is neglected or introduced by taking an average height between the maximum and the minimum height of the power line [6][7][8].…”

This paper proposes a 3D quasi-static numerical model for the magnetic induction calculation produced by the high voltage overhead power lines by using the Current Simulation Technique (CST) combined with the Particle Swarm Optimization Algorithm (PSO), in order to determine the appropriate position and number of the filamentary current loops for an accurate computation. The exact form of the catenary of the power line conductors is taken into account in this calculation. From the simulation results, the effect of the conductor sag is largely noticed on the magnetic induction distribution, especially at the mid-span length of the power line where the magnetic induction becomes very significant, the maximum magnetic induction strength at 1 m above the ground level recorded at mid-span point is 8.87 μT, at the pylon foot, the maximum value is significantly reduced to 3.94 μT. According to these values, we note that the limits set by the ICNIRP guidelines for magnetic induction strength are respected for occupational and public exposure. The simulation results of magnetic induction are compared with those obtained from the 3-D Integration method, a fairly good agreement is found.
