Jul 14, 2017 · When the transformer windings are drawn, a particular high voltage winding corresponds to the low voltage winding drawn parallel to it. In other words, a high voltage winding and a low voltage winding that are drawn parallel to each other constitute a single-phase transformer or two windings on the same leg of the magnetic core of a three-phase ...

Refer to single line diagram: HV-E-03-01. The HV circuit breaker is capable of switching transformer in and out as well as isolating the transformer from the 345kV side under fault conditions. The interfacetransformer (T1), 34.5 /345 kV rated 84/112/140MVA (ONAN/ONAF/ONAF), steps up the solar farm collector system voltage from 34.5 kV to 345 kV.
