Answer Posted / sudhakar g
First we have to calculate the load details
Ex: for 100 kw load
I=(kw*1000)/(p.f* 415v*1.732)
=173A
For cable manfacutrer they give the list of for these amp
how much cable we have to lay
If u want to calculate means u have to consider
1) derating factor
2) temprature coffiecent factor
3) kfactor

If any HVDC line is going with positive & negative(the negative usually have return path of current with earthing electrode). Now the question is if this HVDC earthed electrode which is using as return path and earthed any nearby 400kv or 220kv AC substation equipments. which will be the impact of this on AC substation & its equipment, how severe may be this and what should be the minimum distance require between HVDC earthed electrode and AC substation equipments? It's really an high engineering level question...Dare to answer and increase your knowledge.
