The electromagnetic interferance caused by high voltage power lines along the electrical railway equipment

Locating Critical Lines in High-voltage Electrical Power Grids

Nowadays the issue of vulnerability and protection of critical infrastructure is attracting a great deal of attention among scientific researchers. One of the most used approaches is that of complex networks. A critical infrastructure (e.g. a power grid) is represented as a graph in which nodes represent the main components of the network (e.g. power plants or trasmission substations) and edges...

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...

genotoxic effects of electromagnetic fields from high voltage power lines on some plants

allium cepa bulbs were germinated in pots for three days on treatment area on which 380 kv high voltage power lines are passing. ten bulbs were set up for each treatment area (0 m (meter), 10 m, 25 m, 50 m and 100+ m for control from power lines). triticum baeoticum boiss. subsp. baeoticum seeds were collected at same distance from power lines on planted field. ten seeds from each area were ger...

Electromagnetic fields and cancer in children residing near Norwegian high-voltage power lines.

The aim of the nested case-control study reported here was to test the hypothesis that exposure to electromagnetic fields of the type generated by high-voltage power lines increases the incidence of cancer in children aged 0-14 years. The study population comprised children who during at least one of the years 1960, 1970, 1980, 1985, 1987, or 1989 had lived in a census ward crossed by a high-vo...
