Step-Up Power Transformer ABB 2 x 8000 kVA, 21/6 kV, 50 Hz

Two identical step-up transformers for mid-voltage step up from 6 kV to 21 kV with capacity of 2 x 8000 kV / 50 Hz.  Transformers were made by ABB in 1999 and they were operating approx. 32000 hours and dismantled in 2021 in full operational condition. They have ONAN cooling system and they are oil filled with external expansion vessels. Outgoing voltage can be regulated with a tap switch from standard 21000 kV +/- 2 x 2.5 %
