Good morning all!
Thanks for your answers, I have found a great article largely answering my initial question: https://www.carbonbrief.org/solar-wind-nuclear-amazingly-low-carbon-footprints/
Here is the conclusion, the last sentence is quite interesting:
Contrary to the claims of some critics...
Hello Physics Forums!
It is only my second post here, so sorry if I am not perfectly following the rules...
We were wondering with some colleagues a few hours ago, what is the threshold where PV panels are adding a carbon footprint to the electricity generated on the grid considering the...
Thanks a lot all of you! That was quick.
So first reduced insulation between LV and center core than with HV and center core (meaning smaller and cheaper transformer). Make sense.
Then second, it's easier to place the tap changer on the outside than on the inside of the winding, ok I guess...
Thanks for the welcome!
You are right, I was a little light on details. I am talking about a Generator Step-Up transformer going from 840V to 33kV, let's say around 5MW, 3 phases with aluminum windings, is that enough? Do you think that some HV transformer have their HV windings on the "inside"...
Good morning all!
I have a quick question regarding high voltage transformers, can someone explain why we need to put the low voltage winding the closest to the core and the high voltage winding on the "outside"?
Have a nice day!
