@jalsup To clarify, do you want me to draw something like this, but the loop simplified a bit, maybe three single phase pad mounted transformers respectively on phases A, B, and C?
It would look something like this, but the assemblies for xfmrs will be simpler and I'll make it into a loop. What is that device at the beginning of the loop above, a switchgear? Or a junction box?
that should work. Open one elbow on each transformer, so we can show the three point points.
This is rough and incomplete, but am I on the right track? If the start of loop is a junction box, I think I can fit it but it will be tight
I see that I need to switch H/L terminals on the xfmrs
I don't think we should include the junction box, to me it is making it too confusing. Just have the three sets of lines going straight across. But, you do need to add the Trench as a container.
Good?
is there more than 1 SP per xfer bank? Should we show a 1:M notation if so?
SP is missing from key
Good catch
perfect!
Create a diagram to show the correct way to model a Underground Residential Development using Medium Voltage 3 phase underground lines used with Pad Mounted Single Phase Transformers. There should be a "loop" where an open point is created by opening one of the elbows on one of the transformers half way in to the loop (think cul-de-sac). Also, the Three Phase lines would actually be 3 single phase lines contained in a Trench using containment.
