Transformer fires are not that uncommon and aren't related to the nuclear side of the plant.

that's right.
however, I want to warn the Russian slander in the future. :)

Is this the same unit which has been tripping due to transformer issues?

I'm speculating they might have bypassed transformer trips and didn't do sufficient oil analysis to determine if the transformer was good or not. Or maybe a common mode problem with transformers (unlikely but possible)Edit: different site/unit

There were events at Zaporozhiya, Unit 3 nuclear power plant tripped on 28 November, and at Unit 6 in December. The current event deals with South Ukraine Unit, which apparently had transformer malfunction.
