Could anybody could give an idea who use CDEGS software. I have the measured ground resistance in summer when the sub is connected with distribution neural. So I model the sub in MALZ and give GPR energization= given fault current x measured ground resistance. But when I want to model in winter increasing the soil resistivity, I could not use GPR energization since I don't have winter ground resistance measurement data. So do u have any idea how I model the winter model.
