What does the line circled in red represent on this transformer name plate? View attachment 22878
No.Corner grounded delta would be my guess. Not that I've come across any here in UK.
I apologise and stand corrected.No.
The corner ground symbol would be outside of the delta and contain a 'ground' symbol.
Because this is a dashed line internal to the delta, it provides information on the angle/relationship of the windings. It is used with a comparable dashed line on the diagram of the secondary. I believe the typical wye secondary dashed line is hidden by the neutral point grounding symbol.
I am presuming since X1 is shown with a horizontal line, the number of degrees from horizontal the line in question is - is the phase differential here?it is showing the phase shift between the H and X windings
