Hello everyone!
I have seen a huge tranformer when I was working as a transformer cleaner. This tranformer was quite unusual, because one of its side had many connections I couldn't recognize what is it for. I want to understand what was the function of them.
On the first picture you can see the whole transformer with its dangerous connection terminals. The cables in question are connected to the tranformer at the yellow stickers with numbers. They seem to me like taps on the transformer, described on http://www.allaboutcircuits.com/textbook/alternating-current/chpt-9/winding-configurations/ However, I just don't understand why this side has taps. I think this is the higher voltage side. Why people would like to gain more voltage levels on the higher voltage side? If these are a taps, what could be the function of getting different levels of very high voltages?
