Benefits of Using Electric Assembly Features When There is Only One Content? (Electric UN)

Hi,

We're working on making small adjustments to the ESRI's Electric Asset Package/Solution to better fit our needs. For a little more context, we're starting with no previous GIS/Geometric Network data to migrate; this is a jump from paper maps to the UN.

 

At this point, we're focused on understanding and selecting the AssetGroups and AssetTypes that we need to model our infrastructure. Also, we're identifying additional attributes we would like to add to the selected AssetGroups.

 

Looking at the Naperville sample model we noticed some of the uses of the ElectricAssembly features that made us ask if there are benefits that we don't understand. For example:

 

  •  Medium Voltage Power Factor Correction Bank (Assembly) ---> Contains ---> One Overhead Three Phase Capacitor (Device): In this case there is only one device contained by the assembly, the visibility is set to visible in the association status and in many cases they are graphically on top of each other.
  • Low Voltage Service Bank (Assembly) ---> Contains ---> One Low Voltage Service (Device): In this case there is only one device contained, but if there where 10 or 20 customers fed from the service bank would the expectation be that 10 or 20 Low Voltage Service features will be contained in this assembly? Or, a related stand alone table with this customers details and meters data  would be more beneficial?
  • Medium Voltage Switch Bank (Assembly) ---> Contains ---> One Medium Voltage Switch (Device): again a single device contained, and most of the time graphically drawn on top of each other.

 

We understand the benefit of an Assembly containing multiple features, like a transformer bank that contains individual feature representing transformers, fuses, arresters, and connector; or a pad mounted switch bank that contains elbows, busbars, switches, etc.  But what are the benefits in the examples above? Why not just used the Assembly or the Device only?

 

Also, we noticed that only the Assembly has an attribute for "Subnetwork name" but not the Device inside (see picture below)
