Rivne's switchyard move

摘要

In September 2012, reserve transformer 6TR was commissioned, completing a plan to provide 6kV backup power to Rivne 1&2 (also known as Rovno in Russian). The need for a second backup transformer for the twin WER-440s at Rivne first became apparent in 1981, after startup of Rivne 2. While one 32,000 kVA standby transformer (type 1TR TRDN-32000/110/6, 3/6, 3) was sufficient for one unit, it was not for two.
