| dc.description.abstract | High voltage on transmission lines creates electromagnetic field effects in the
surrounding area, one of which is the electric field effect. The electric field from the
transmission network will affect conductive objects below it, such as a house roof. Because
of the induced electric field from the voltage wire, the roof becomes charged and creates a
potential difference with the ground. This study observes the effect of surrounding objects,
such as height, number, position, resistance, and cross-sectional area, and varies the
ground resistance to see the effect of induced voltage on the house roof. This study uses a
dimensional scale, with a 1:7 ratio of actual size. Based on the analysis that has been
carried out, it can be concluded that the resistance of surrounding objects can affect the
induced voltage on the house roof. The greatest effect on reducing induced voltage occurs
with a wet object resistance (104 Ωm) rather than a dry object resistance (106 Ωm).
Furthermore, based on this study, the magnitude of induced voltage is proportional to the
height and cross-sectional area of the surrounding objects, but for the number of objects,
there is an effect of the position of the surrounding objects. The more objects that are
aligned directly below the transmission network, the smaller the induced voltage on the
house roof. In this study, the smallest induced voltage occurs with a wet resistance object
(104 Ωm) at a height of 1.5 m, a cross-sectional area of 0.0025 m2, and four surrounding
objects with a position of one on the left and three on the right. In this study, the effect of
ground resistance itself can be said to not significantly affect the induced voltage on the
house roof because the difference in induced voltage values for each ground resistance
variation is not significant. | en_US |
