Ground Grid Study
Ground Grid Study
(OP)
Hydro provides customer with maximum and minimum short circuit currents as well as max Z and Z0 values.
If the ground grid study needs to be done. I was told to use Max( L-L-G, L-G) for ground fault.
Why do we need max and min values? Where Min is used in calculation?

Minimum values are also used when performing Load Flow or Motor Starting studies.
