Hello,

I have a service fed by 2 - 100kVA transformers set up as an open delta. The primary side is connected as a grounded wye at 46kV and the secondary is a open delta with a center tap. The secondary voltages are then 120/240 and 208.
How would you model this for arc flash hazard?

For arc flash analysis, I would model it as a full delta with 240V phase to phase voltage.
