I have been to a substation visit with the college. We visited an inside 120/10 kV substation.

This is a part of the old control panel. The operator work on computer only, the panel is good for control the measuring.

In Budapest is 10 kV earth cable power system only, the open wire network is really rare. In suburb are open wire network, but they are working on 20 kV. In the city everything run in underground..
