“…It has been shown earlier that the conductor height has a significant influence on the electric field, and ion current density under dc power lines [1,7]. In the following, the height is considered to be the only random factor influencing the frequency of occurrence of E and J.…”

“…With the growing need for electric energy, direct current has been, recently, established as an attractive economical and operational alternative for transmitting large bulks of electric power over extra long distances [1][2][3][4]. The ion-flow electrification phenomenon, caused by ionic conduction through the air and associated with dc power transmission lines, usually characterizes the potential biological impact of exposure to dc ionized fields [5][6][7]. Two fundamental parameters; the electric field and ion current density, are denoted in this regard [5,6].…”

An integrated statistical approach, based on Monte Carlo simulation, is developed in this paper for probabilistic exposure assessment under HVDC transmission lines. The validity and adequacy of traditional, deterministic, models for HVDC ionized fields have been repeatedly questioned in literature. The present work recognizes the probabilistic nature of the exposure variables, electric field intensity and ion current density, and caters for their inherent uncertainties in order to simulate the realistic dc line environment. Randomness in the factors influencing the ionized field quantities is identified and accounted for, namely, the wind speed, the line sag, the corona onset gradient, and the location of objects under the line. Based on an overall probabilistic approach, the integrated influence of these factors on the exposure parameters is evaluated and assessed.
