Issue:
Feeding of Medium Voltage Transformers
Product Line:
Medium Voltage Transformers by SquareD/Schneider Electric
Environment:
Installation of MV Transformers
Cause:
Connection variations of MV Transformers
Resolution:
Radial feed Transformers will have three high voltage bushings (H1, H2, and H3). There is one bushing for each phase to allow for the incoming high voltage cables. On Wye and Grounded Wye connected Transformers, there will also be an H0 bushing.
Loop feed Transformers will have six high voltage bushings (H1A, H2A, H3A, H1B, H2B, and H3B). There are two bushings for each phase. This allows the customer to connect all of their Transformers in a loop configuration. It will also allow the customer to bring two feeds to the Transformer. A four position switch can be used to switch between the A feed and the B feed.
