This article discusses the characteristics of high voltage power line carrier channels over underground cables and mixed cable-overhead high voltage power lines. It shows which modal parameters underground cables have and how junctions of overhead power lines with power cables influences to the parameters of PLC channel.

Electric field mitigation under extra high voltage power lines
IEEE Transactions on Dielectrics and Electrical Insulation, 2013This paper deals with the mitigation of electric fields under extra high voltage transmission lines using active and passive shield wires. Two extra high voltage alternating current transmission lines are modeled and analyzed. One line is operating at 220 kV and the other is at 500 kV.

High-voltage power lines near wild reindeer calving areas
European Journal of Wildlife Research, 2015Within ungulate home ranges, suitable calving areas are of crucial importance for maintaining the reproductive potential of populations. Using GPS telemetry from a unique time series spanning before, during and after the construction of a 420-kV power line, we present results on calving site locations and area use during calving for two wild reindeer ...

Fault diagnosis in an extra-high voltage power line
2017 IEEE PES PowerAfrica, 2017The use of fuzzy and adaptive neuro-fuzzy technique for fault detection, classification and location is presented in this study. Ten different types of electrical faults in a transmission line were investigated. The results obtained show that a high degree of accuracy was recorded for detection, classification and location of electrical faults in the ...

Residential development close to high-voltage power lines
World of Real Estate Journal, 2019Purpose– The progressing urbanization of cities makes it necessary to develop larger areas of land for housing development both in urban areas and on outskirts of cities. This often results in housing developments inevitably approaching high-voltage power lines built several years ago.

Efficiency of High Voltage Transmission in Power Lines
The Physics Educator, 2019In introductory Physics courses, one might come across a question of why electricity is transmitted from the power station at high voltage? Analysis of a typical quantitative question is illustrated in this paper, showing its deficiencies. An alternative method that mimics more closely to realistic situations is proposed to better illustrate the ...

ACCIDENTS ON HIGH VOLTAGE POWER LINES
Electric transmission lines differ according to the probability of accidents occurring in them according to the voltage class they belong to. Thus, the vast majority of accidents that occur in 10/6 kV power transmission lines are caused by leakages in transition insulators of line wires at transformer stations and accidental contact of tree branches ...openaire +1 more source
