PENGARUH KETEBALAN BATU KORAL PADA TANAH LEMPUNG DAN TANAH BERPASIR TERHADAP TEGANGAN LANGKAH DAN TEGANGAN SENTUH
Main Article Content
Ground fault currents that flow in the disturbance area and in the switchyard area of the
Substation create tension on the ground which can result in touch voltage and step voltage that
exceed the allowable limits of human safety. The thickness of the coral rock affects the value of
the touch voltage and step voltage. This research was conducted to determine the effect of the
thickness of the coral rock on clay and sandy soil on stepvvoltage anddtouchvvoltage.The
method used is by measuring coral, clay soils and sandy soils, then calculating thevvalue
ofttouch voltageaand stepvvoltage based on the thickness of the coral used. The results of
calculations and analysis of several thicknesses of coral stones used in clay soil, obtained the
results of the touch voltage in the dry state of 153.5615 volts and in the wet state of 152.0702
volts, the results of the step voltage in the dry state 188.5057 volts and in the w et state 182 ,
8265 volts. On sandy soil, the results of the touch voltage are 153.6893 volts in dry condition
and 152.1981 volts in wet conditions, the results of the step voltage in dry conditions are
189.141 volts and in wet conditions 183.4349 volts.
