In the simulation of earthed systems earth ressistance is to be included, What is its nominal value
Narasim Ramesh
hi
Suggest you can model it as an infinite hemisphere with earth resistivity.
ref :https://en.wikipedia.org/wiki/Soil_resistivity
"The soil resistivity value is subject to great variation, due to moisture, temperature and chemical content. Typical values are:
Usual values: from 10 up to 1000 (Ω-m)"

You can use the ground block available in SIMULINK. In general earth resistance is of order of 1 ohm.
