Standard Overhead Service

[MikeMillerGIS]

There are three examples of the standard overhead service that would be important to show.

• [ ] Single Service from Overhead Single Phase Transformer
• [ ] Two services from Overhead Single Phase Transformer where the low voltage overhead man makes a "V" such that the bottom of the V is at the Transformer.
• [ ] Service tapped from overhead secondary running in parallel to Distribution Medium Voltage circuit on poles.

Single Service from Transformer

• [ ] Overhead Single Phase Transformer
• [ ] Low Voltage Overhead line from Overhead Transformer, Low Side terminal to Service Point
• [ ] The Low Voltage Service Point, Residential
• [ ] A Structure Junction/Electric Low Voltage Pole mid way between the transformer and the service point
• [ ] A Low Voltage Connection Point/Attachment
• [ ] The Structural attachment between the Low Pole and the Low Voltage Connection Point

Two Services from Overhead Transformer using same Low Voltage line

• [ ] Overhead Single Phase Transformer
• [ ] Low Voltage Overhead line from Overhead Transformer, Low Side terminal to Service Point
• [ ] Two Low Voltage Service Point, placed at the corner of adjacent homes
• [ ] A Low Voltage Line between the two service points such that the line forms a V with the bottom tip of the V located close to the Overhead Transformer
• [ ] A Low Voltage Overhead Tap placed on the Low Voltage line at the bottom tip of the V
• [ ] A Low Voltage Connection Point/Attachment close to the bottom Tip of the V but not coincident with the Tap
• [ ] The Structural attachment between the Medium Voltage Pole and the Low Voltage connection point/attachment

Service tapped from overhead secondary

• [ ] Three more more Poles (any type)
• [ ] Low Voltage/Overhead line running between the poles, not split at the poles
• [ ] Low Voltage Service Point somewhere away from the line above
• [ ] Low Voltage Connection Point/Tap at the middle pole on the low voltage line
• [ ] Low Voltage/Overhead Line running from the Tap to the Service Point

John, this is my interpretation of your first case. I took the liberty of adding a service point at the next point/tap/attachment of the secondary underbuild.

Your second case is confusing me. I'll have to carefully plot that out on Monday morning, my brain is full now.

Question: on the left side of the secondary underbuild, is it correct to add an attachment from the line end to the pole? I'm asking because in other cases, like the junction box, recloser bank, transformer banks, we had distinct line ends and attachments and only added a attachment relationship from attachments, never from the line end. The same issue applies to the bottom service point. I remember talking with Tom last year about this issue and I think we allowed structural attachments from line ends then, but I'm not sure what our current model pattern is. This boils down to: is the only junction feature that an attachment can be made from is the attachment features?

Change structure point to structure junction

Ok, I think this is what you mean above. I also added an attachment feature to the secondary line so it is properly attached to the top-left pole. One thing bugs me: when I try to visualize this in the field, I think they are in fact two separate physical secondary lines.

looks good!
