Distribution Connected Solar Transformer Grounding
Selecting the inverter transformer winding configuration, whether Grounded Wye-Delta (YNd1) or Wye-Wye (Yy0) or others, can be challenging for the electrical design engineer or developer. Often, inverter and interconnecting utility requirements add complexity or force a particular option. This poster provides lessons learned from the result of multiple projects from design to commissioning.
