What is a substation used for ?One of the main goals that every electrical utility company has is transportation of electrical energy from the generating station to the customer, while meeting the following main criteria:
High reliability of power supply Low energy cost High quality of energy (required voltage level, frequency etc.)

Why grounding is important ?
1-Path for short circuit to remote earth2-Provide safe step and touch potentials
Grounding system design consists of all the following :Grounding rods Grounding grid Copper cables Equipment connectors
Main safety issues in grounding to be concerned about in designing the grounding system :
Touch Voltage : Voltage difference between equipment being touched and the ground at your feet
Step Voltage : Voltage difference in ground between your feet as you are standing or walking
GPR ( Ground Potential Rise ) - V = I * R -Fault current into the grounding system times resistance to remote earth
