Greetings,

I am using CYMGRD to design a substation ground mat for a 33/11kV substation. However there is a discrepancy in the maximum touch potential in the potential contour report & potential profile report.

In the potential contour report, the maximum touch at potential is 1451.21 volts, meanwhile in the potential profile report it is 994.851 volts.

Any suggestions as to why such a difference exists?

I have attached the reports for your reference.
