    I want to design the earth mat of a 33/11 kv substationat kanpur for which i want to know the fault current the resistivity we have found 22 ohm met and IEEE80 formule is not available,there fore I WANT YOUR HELP

    Among the inputs data, i don’t understand what you mean by the following, which is both required in your program:
    i) Reference Depth of Grid and Depth of Earthing Grid Conductor
    ii) Diameter of Earthing Grid Conductor or size of earthmat flat
    iii) Number of adjacent earthing mat conductors
    iv) How evaluate the values Ks, Df

    Kindly explain what you mean by these terminologies, and where to get such inputs.
