Trying to decode the journo-list speak (the Ukranian would be easier to decipher), the various reports sound more like a main transformer fault. If it were a transformer metering issue or failed PT/CT, it should be repaired soon. If it isn't back soon, then I'm guesstimating failed winding insulation as root cause. Looking at that unit being offline for months if that is the case.
In any event the report is indicative of the negative press bias our industry suffers. This same type of thing happens at US plants a few times a year, an electrical fault causing a plant trip, yet this one is characterized as an "accident." It has made the headlines at several national and international MSM news sites. And the story is bent to clearly change the significance, e.g. "Chernobyl, pro-Russion part of Ukraine, etc. It is clearly intended to be a "sensationalism" headline, not news. And that is the real problem, not the plant trip.
Looks like Unit 3 is raising power slowly, up 10 MW or so since last hour when checked....
Just another generator trip, nothing to see here. Unit 3 again though, perhaps relay issues or time for exciter maintenance?
