Determination of starting point while performing trace operation in Electric UN

[AbigailMiller]

Hi Folks,

I am working with Electric Utility Network downloaded from ArcGIS Solutions (Electric Utility Network Expanded) and then created UN out of it in file geodatabase

I am trying to run a downstream trace operation on tier Electric Distribution Primary, however, while choosing the starting point ( a valid device with a subnetwork controller) and running the trace gives error 001981: one or more starting points outside tier. The same issue was encountered with the Electric secondary tier as well

I am a newbie trying to figure out how to work with the UN. Performing this operation is an urgent project requirement.

Would be great if someone could tell me and let me know how to choose or prerequisites for choosing starting points for tiers while running trace.

Any kind of insights will be highly appreciated.

Regards,

Abigail

If you are just trying to get the content of a subnetwork, use the subnetwork trace and pick the name of the subnetwork you want to analyze.

The most likely scenario is that when you are placing your trace location on the subnetwork controller, you are not selecting the terminal appropriate for your trace. As an example, if you're trying to do a distribution trace on a circuit breaker, you need to pick the line side terminal because it is the distribution side of the circuit breaker. If you select (or default to) the bus side terminal of the circuit breaker, you are actually looking at the transmission side of the circuit breaker.

Can you post a screenshot of the your trace locations pane, your trace gp config, and a map showing the feature you're trying to trace?

Hi Robert, 

Thanks for the insight.

I am using the device (high voltage Transformer--Arc Three Phase HV-->MV) as a starting point for the trace. I am trying to share the screenshot however am unable to upload the images.

Hi @RobertKrisher 

Seems like I cannot upload the images. Is there any way I can share the imageries with you?

[RobertKrisher]

You can try dragging/dropping them or use the insert photos button. If that doesn't work, you can just type out answers to my questions.

[RobertKrisher]

Which terminal have you selected on the device, what is your trace type and trace configuration, which specific feature (global id) are you using?

Hi @RobertKrisher 

I am using  starting Point [High Voltage Transformer/AC Three Phase- HV--> MV {GLOBALID: E346313E-1DBB-4641-BB11-AE442CB4F5A8}]; Trace Type is Downstream Trace; Input Tier: Electric Distribution Primary; Domain: Electric

Ah, two problems:

1 - That transformer doesn't have any distribution on its low side and isn't set up as a subnetwork controller. It belongs exclusively to the transmission system. Try using transformers that are set up as subnetwork controllers for the distribution tier, there are quite a few of those to choose from in the sample dataset.

2 - The tier you're looking for is the distribution tier, that's the standard radial distribution tier. If I do a trace using that tier and the criteria mentioned above, I get results (Example below is transformer {666C507B-3094-43C6-B284-C462D191ABA2}).

If I set the target tier to also be a lower tier in my network, it will also trace the distribution circuits downstream of this subnetwork.

Hi @RobertKrisher ,

Thank you for the insight. It worked.
