Circuitlengteveld in Subnetregel wordt niet gelezen als netwerk in Secondary Mesh Tier

RomuldKiobya

Gebruik van ArcGIS Pro 2.9 als contract met de klant

Onze klant heeft distributie (MV en LV) netwerken, transmissie- en generatie netwerken. Maar voor het probleem van distributie in MV-netwerken en transmissienetwerken.... wordt de circuitlengte perfect gelezen. Het probleem ontstaat wanneer ik LV voor klanten heb gemaakt). Ons traditionele LV-netwerk heeft servicelijnen naar klantmeters EN transformator distributielijnen vanaf HRC zekeringen. Maar omdat HRC zekering niet bestaat als Assettype en subnetwork controller, hebben we besloten om HRC zekering te vervangen door LV Network protector ...om een subnetwork controller te kunnen maken). En we hebben een gedefinieerd subtype toegevoegd aan de low voltage conductor assetgroep genaamd Service line overhead en underground.

In Tanzania Elektrisch netwerk Infrastructuur op het LV-niveau

MV transformator (11kv of 33kv naar 440V)----HRC zekering--Transformator distributielijn - Servicelijnen----Klantmeters

Arcgis netwerk ((in de Secondary Mesh Tier)

MV transformator (XFR low) verbindt met Network protector (vervangt HRC zekering)-----LV geleider Ac overhead(vervangt Transformator distributielijn)------Servicelijnen overhead (Servicelijnen)- lv services (Klantmeters.

The circuit length that is calculated is based on the units of measure of the spatial reference of your utility network dataset. So, in your case, where the units of measure are meters and you want to see it in kilometers you are correct that you will need to add a new field to your subnetwork line class and calculate the value for all your existing subnetworks.

To maintain this field going forward I would recommend you consider creating an attribute rule on your subnetwork line class to calculate this field every time a new subnetwork is created or updated. Running a script every night to recalculate this field is not recommended.

Open the Set Subnetwork Definition tool, select your low voltage tier, and look at the Subnetwork Trace Configuration > Summaries section. You will see that there either isn't a summary for calculating circuit length on this tier.

You should be able to add a summary with the function of "Add", on a network attribute of "Measured Length" into the "circuitlength" attribute. Every model is a little bit different so if some of these attribute names don't match up you should use the same configuration as in your distribution/mv tier but remove the filter (that limits it to MV conductor).

The circuit length is calculated using the measured length of all medium-voltage conductors in a subnetwork, so it would make sense that it isn't being calculated for your low-voltage tier.

Your idea gave a blueprint for a solution. But I ask what the unit of Circuit length is if it is in Meters. My client needs in KM, can I add a new field in the Subnet line feature class and create the calculation = Circuitlength/1000?. Attached file below

I saw this document on Esri blog on Subnetwork length https://pro.arcgis.com/en/pro-app/latest/help/data/utility-network/subnetwork-trace-configuration.htm#ESRI_SECTION1_DFCC58FE530C4AC0A6DC33B417EA0065

I want to change measure length to shape length to get meters
