Referring to this ArcGIS Utility Network Question https://community.esri.com/t5/arcgis-utility-network-questions/connectivity-trace-setting-up-combined-condition/m-p/1569491#M4697 I hereby suggest a change. In the above-mentioned question, @MikeMillerGIS states that the behaviour is as designed. I urge a change in this design then, so that setup condition barriers may work across all tiers rather than only within the initial tier. I honestly do not see when I would want condition barriers working only on the initial tier, yet when changing the behaviour so that condition barriers may work across tiers it should be simple to add this as an option (Condition barrier working only on initial tier - yes/no). Happy New Year to everyone out there ... View more

Hi there Need to do a connected trace stopping whenever encountering a low voltage cable or a low voltage overhead line. ElectricLine::37::Low Voltage Underground Conductor::102::AC Underground LV ElectricLine::6::Low Voltage Overhead Conductor::100::AC Overhead LV This is done using condition barriers - in SQL I would create a query like (ASSETGROUP = 37 and ASSETTYPE = 102) or (ASSETGROUP = 6 and ASSETTYPE = 100) Using the GP tool I would set it up like this: How do i know that ArcGIS does an (A and B) or (C and D) and not a A and (B or C) and D? It's the first combination / query that I need. ... View more

In an electric grid having a section of the grid de-energized due to open switching devices between it and one or more subnetwork controllers I need Utility Network to offer a trace telling me potential switching devices to close in order to re-energise this section. At Esri UC 2024 I discussed this with David Crawford and he suggested an approach that could bring me some of the way, yet may output false positives. Let me explain. I place a trace starting somewhere in the de-energised section and initiate a Connected trace. This connected trace is configured with Condition Barrier Operating Status Normal equals Open This will make the connected trace stop at open switching devices. and with Output Condition also set to Operating Status Normal equals Open This will make the connected trace only return these open switching devices. And it does return open switching reachable from the trace starting point placed within the de-energised section of the grid. So far so good. Yet, in case of loops within the de-energized section or open switching devices to a customer currently disconnected the trace result will include open breaker not allowing in-feed. False positives. You guys, Esri, have the entire graph model in the background and I assume it's feasible for you guys to offer a trace capability / configuration returning only the open breakers which upon closing would in fact re-energise the section in question without including false positives. Looking forward to your answer and fix. Love how at Esri UC you can go to the expo, find the right booth and always find the knowledgeable person answering your questions ❤️   Best regards   Jens Dalsgaard Volue ... View more
