Thanks for the replies.
waross --> I'm sorry...I stated the transformer high-voltage side incorrectly. It is not an "open" delta. It is an ungrounded delta...3-phase at 138kV. Not sure if this makes a difference in your reply to my original post.
My objective is to ensure that the voltage...
I am working on a project to add kW/kVAR transducers to an existing 3-phase system. There is a 13.8kV-138kV step-up transformer in this section of bus. The 13.8kV side is grounded wye and the 138kV side is configured as an open delta. All of the current transformers (C/Ts) on the 13.8kV side...
