Voltage drop and short circuit current of a mining cable
Voltage drop and short circuit current of a mining cable
(OP)
I need to make calculation of voltage drop and short circuit current for some mining cables. Cables are supplying variable speed asynchronous motors, and 5th and 7th harmonics are present. Motors are using ABB's ACS800 dives, with some modules added. I need to add influence of harmonics on voltage drop and short circuit current in my calculations. If anyone knows what are the relevant IEC standards on this matter, please give me a hand :).

This would get you in the ball park. You can then look at some IEEE references or other publications to add a factor or so for the harmonic curent contributiuon.
This would be a good first order approach.
