This paper addresses the issue of the
interaction of the human body with power frequency
(50/60 Hz) magnetic fields. Two human body models
are used; a simple spheroid based on an analytical
method and an approximate human shape based on
finite element method (FEM). The employed human
body models are positioned in two magnetic field
sources; under a power transmission line and inside an
electric power substation representing typical exposure
cases. The magnetically induced currents inside human
body due to the exposure to power frequency magnetic
fields are evaluated. A number of parameters such as
human dimensions and proximity to the current-carrying
conductors are considered. A comparative analysis of
the magnetic induction inside the human body due to
the different human models and magnetic field sources
is also presented. |
