Hello everybody,
What is shaft and bearing current? How does it occure? What are the indications? How can you measure? is there any thread about this topic before?
Thanks in advance.

Hi,
What is your explanation for this paradox? (at least for me!)
1. The insulation resistance decreases if the heat is increased.
2. The current carrying capacity decreases if the heat is increased. (it means the conductivity decreases so the resistance increases...)
it seems a paradox...
Hi all,
Everyone knows the current carrying capacity of the busbars increases if the busbar is painted. WHY? it looks simple but i couldn't find any reasonable solution. Can you help me please?

Who knows something about "recurrent surge osciloscope measurement method" will be done on the rotor of synch. generator?. Would you like to share your knowledge with me?
thanks.

Hello all,
We have 4 generators star point grounded through the PT, 8 MVA each. Step up transformers 11/34,5 kV; 8 MVA; Delta-Wye; connected. These four groups paralleled on 34,5 kV bus and one synchronizing breaker connect the bus to the network. The question is we have just one neutral...
Hi guys,
I need a powerfull short circuit, load flow and voltage drop calculation program. I will calculate a generation+consumer systems and will make relay co-ordination. There are araound 600 relays (different types-oc/ef). Could you advise me which one i must sellect and what kind of details...
