Current Density Induced in the Human Body due to Power Distributions Lines using the Boundary Element Method
نویسندگان
چکیده
The paper presents the human exposure assessment to Extremely Low Frequency fields (ELF) by means of the three dimensional Boundary Element Method (BEM). The formulation is based on a rather realistic representation of the human body. The paper analizes the response of the density current due to variations on the detail of the conceptual model considered. Variations on the geometry model and the inclusion of organs have been considered. The results obtained with and without considering the rough representations of the internal organs were compared. This comparison allows to estimate their relevance in numerical modellings at ELF.

متن کاملDetection of power oscillation and simultaneous faults using Clark transform
Distance relays are widely used to protect transmission lines. Sometimes, in these lines due to the occurrence of the oscillation of the power, the impedance calculated in the distance relay enters into its functional zones and leads to the cutting off of the lines. This issue can cause global power outages. Accordingly, in this paper, a Clark-based method for detecting the oscillation of power...
