Abstract:

The article summarizes the results of research in four selected sites (observations) on the impact of surface power lines on bird death in the area of Nakhchivan Autonomous Republic in 2016-2017. Studies show that electrical wires have a major impact on bird death during the spring migration and nesting period. We determined that 225 individual of 27 species were killed by electric shock in selected areas, while 16 individuals belonging to 3 predator bird species were exposed to this threat. Two of these species are in the World Red List. The next plot with high mortality rate was the Cananbar

Abstract:

Electrocution mitigation is frequently the first step electric system operators take to manage raptor mortality on overhead electric systems. As electrocutions are addressed, operators often begin to distinguish carcasses found under pylons (electrocutions) from carcasses found mid-span between pylons (collisions), and begin to identify avian concerns in electrical substations, including raptor electrocutions. Each of these concerns, mid-span collisions and substation electrocutions, can involve raptors. This presentation will summarize the current state of the art in managing avian collisions

Abstract The literature on bird collision with power lines in Hungary is rather limited. We collected published records and carried out research on birds that collided with overhead wires, and we made a list of species, and the number of individuals recorded, around Pusztaszer Landscape Protection Area. The quality of data did not allow us to do robust statistical tests, and a large amount of collected data was not used in this paper, because of uncertainty. Finally, we used the records of 519 individuals of 63 species that got injured or died during collision with overhead wires. We found evi

Abstract The main reason for line collision accidents in offline construction is that construction personnel have an insufficient perception of distance. In the range of viewing angles, due to the lack of reference objects, people lack a correct judgment of the actual height of overhead lines. Voltage, as the most direct electrical volume, has always been a key indicator of electrical protection. In this paper, the feasibility of electrostatic induction is verified through the combination of electrostatic field simulation and experiment, and the influencing factors of electrostatic induction a

This paper discusses effect of phase sequence layout on electric field under overhead lines. Charge simulation method is used. Examples of two circuit overhead lines and four circuit overhead lines show that phase arrangment of lowest height conductors has major influence and phase arrangment of middle height conductors has lesser influence on electric field under overhead lines. Interlacing placed lowest height conductors with different phase and phase arrangement of middle height conductors different from that of lowest height conductors help to reduce electric field.

Ultra High-Voltage Overhead Lines (UHV OHL) currently are successfully applied for solving two problems. The first case is powerful interconnection of two or more electric power systems. The second one is transition of significant power flows from generation areas to consuming areas – densely populated urban agglomerations and industrial centers. Longitudinal compensation installations are integral part of long-distance UHV OHL. The possibility of designing self-compensated OHL is considered in the paper.

Unmanned Aerial Vehicles (UAVs) may offer a less dangerous, less costly alternative that is also less disturbing to wildlife.

Abstract:

This paper introduces a comprehensive process based on inspection for determination of medium voltage (MV) overhead line condition and it was tried that all factors influencing the outage of distribution network integrated into one index that called condition index. A condition based failure rate model has been proposed and its unknown parameters are calculated based on historical data. Shortest path problem (SPP) model has been proposed for the long term scheduling of maintenance and reinvestment. Objective function includes sum of the reinvestment, maintenance costs, failure costs and energy

This paper calculates and analyses electric fields generated by high-voltage overhead power transmission lines. These fields have significant implications for safety and design considerations. The study utilises a numerical technique to determine the electric field distribution in regions containing multiple charges. Based on this method, a computer program is developed to calculate the electric field profile at ground level and two meters above ground level for both 400 kV overhead power lines. The results demonstrate the method's effectiveness in accurately computing the electric field inten

SummaryLudwig’s Bustard Neotis ludwigii, endemic to Africa’s south-west arid zone, is susceptible to collisions with overhead power lines. Limited data from the south-eastern part of its range suggest that this factor may threaten its survival. We estimated transmission line collision rates for Ludwig’s Bustard across its South African range to assess the effect of this mortality on the population. Conservatively, collision rates averaged at least 0.63 ± 0.12 fatal collisions per km of transmission line per year, with relatively little regional variation. Despite being less abundant, the large

To supply stable and high-quality power according to the advancement of industrial growth, electric power companies have performed maintenance of power facilities using various methods. In the case of domestic power distribution facilities, there are limitations in performing diagnostic management on all facilities owing to the large number of facilities; therefore, old facilities are managed using the health index assessment method. The health index assessment comprises only facility operation data and external environmental data and is managed only for four types of distribution facilities i
