Hello All,
I see that in the IEEE 80-2000 Curves to approximate the split factor Sf we have the choice between Transmission line and feeders for the curves.
I understand that transmission line is when you have only 3 phases (HV MV),
and feeders when you have 3 phases + neutral (LV).
It seems...
Hello All,
Why the split factor/current division is no more used in the ground calculation notes, most of the time it will allow to significatly decrease the value of current to the remote earth (from 0.9 for line to 0.1 for buried cables).
But in most of the calculation notes I have see it's...
Hello,
I'm used to made calculation notes on ground grid design. but I would like to know what are the basic and advanced rules for design the ground grid (before improve it and validate or not trough the calculatuion note).
For example how many meters arround the building for substations, how...
