This article will show you how to use the model provided in the Electric Utility Network Foundation<\/a> solution to model your complete electric GIS. If you’re interested in more content like this, I recommend you check out the\u00a0Electric Utility Network reading list<\/a>. You can also try these hands-on tutorials related to this article:<\/p>\n Because the tools and processes used to manage this GIS information are new, we have put together a series of blog posts to introduce you to the language and tools used when working with the utility network to create, manage, and perform quality assurance on the correctness of your electric systems.<\/p>\n"},{"acf_fc_layout":"content","content":" Before we go too much further, we need to discuss the concept of a subnetwork in the utility network. Most networks can be broken down into different areas based on the equipment that is supplying or regulating service. Each of these areas is referred to as a subnetwork, and any feature that manages a subnetwork is called a subnetwork controller. We use these general terms because the utility network is used to model many types of networks and each network has its own definitions for the different types of subnetworks it manages. Each type of resource managed by a utility network is called a domain; the definitions for each type of subnetwork managed by each domain are called tiers.<\/p>\n Most traces in the utility network rely on the subnetworks you\u2019ve created to perform their analysis. These subnetwork traces depend on this information because the system needs to know where the source (or sources) for a subnetwork is to perform upstream, downstream, isolation, and of course subnetwork and subnetwork controller tracing. Once you\u2019ve defined subnetworks you also unlock additional capabilities such as the ability to create and manage system diagrams for your subnetworks and generate an aggregated subnetwork line to represent the subnetwork and summarize important information about it. You can even have the system maintain a field that shows you which subnetworks a feature belongs to or supports.<\/p>\n To learn more about the capabilities and workflows associated with creating and managing subnetworks refer to the Subnetworks<\/a> topic in the online help.<\/p>\n With those definitions out of the way let\u2019s look at the tiers associated with the electric domain in a utility network. The tiers associated with this model are Transmission, Subtransmission, Distribution, and Secondary.<\/p>\n The following diagram shows how the electric tiers are organized, with the higher voltage tiers on the left and lower voltage tiers on the right.<\/p>\n"},{"acf_fc_layout":"image","image":{"ID":1752062,"id":1752062,"title":"Electric Tiers","filename":"Electric-Tiers.png","filesize":25367,"url":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2022\/10\/Electric-Tiers.png","link":"https:\/\/www.esri.com\/arcgis-blog\/products\/utility-network\/electric-gas\/electric-creating-subnetworks\/electric-tiers","alt":"","author":"304562","description":"Electric Tiers","caption":"Electric Tiers","name":"electric-tiers","status":"inherit","uploaded_to":1751972,"date":"2022-10-28 12:48:54","modified":"2022-10-28 12:49:06","menu_order":0,"mime_type":"image\/png","type":"image","subtype":"png","icon":"https:\/\/www.esri.com\/arcgis-blog\/wp-includes\/images\/media\/default.png","width":1983,"height":1155,"sizes":{"thumbnail":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2022\/10\/Electric-Tiers-213x200.png","thumbnail-width":213,"thumbnail-height":200,"medium":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2022\/10\/Electric-Tiers.png","medium-width":448,"medium-height":261,"medium_large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2022\/10\/Electric-Tiers.png","medium_large-width":768,"medium_large-height":447,"large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2022\/10\/Electric-Tiers.png","large-width":1854,"large-height":1080,"1536x1536":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2022\/10\/Electric-Tiers-1536x895.png","1536x1536-width":1536,"1536x1536-height":895,"2048x2048":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2022\/10\/Electric-Tiers.png","2048x2048-width":1983,"2048x2048-height":1155,"card_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2022\/10\/Electric-Tiers-798x465.png","card_image-width":798,"card_image-height":465,"wide_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2022\/10\/Electric-Tiers-1854x1080.png","wide_image-width":1854,"wide_image-height":1080}},"image_position":"center","orientation":"horizontal","hyperlink":""},{"acf_fc_layout":"content","content":" For those of you who aren\u2019t familiar with how electric models are constructed, here is a brief definition of what each of these tiers do:<\/p>\n Now that you are familiar with the purpose of each tier, let\u2019s walk through a few examples of how to create subnetwork controllers in a sample dataset so we have a fully connected electrical system that spans all the way from the transmission to the secondary.<\/p>\n"},{"acf_fc_layout":"content","content":" First, let\u2019s talk about how to create a subnetwork controller. To create a subnetwork controller, you need at least six pieces of information<\/p>\n Even if you\u2019re not familiar with the utility network model, you should be able to quickly identify these pieces of information, with the exception of the terminal. Every subnetwork controller is required to have at least two terminals, one of which is considered to be upstream. The terminals<\/a> on a subnetwork controller allow the system to identify upstream\/downstream flow and in turn ensures that the subnetwork flows in the correct direction.<\/p>\n Once you\u2019ve identified these six items, you\u2019ll want to look at the objects connected to each of your controllers and figure out which terminal on the device they are connected to. This is a straightforward process for things like circuit breakers and transformers, but it may be more difficult in areas where equipment is owned and maintained by one utility and operated by a different utility.<\/p>\n"},{"acf_fc_layout":"content","content":" The first thing we need to check before we create this system is to make sure that the topology for the system is valid. You can still create a subnetwork if you have errors in your data, but you won\u2019t be able to trace or update it until all the errors in the system have been resolved. For this reason, I recommend utilities adopt a zero-tolerance policy for dirty areas and errors in their database! The quickest way to check the number of errors in your utility network is to right-click the utility network layer in your map, select properties, then look at your network properties<\/a>.<\/p>\n"},{"acf_fc_layout":"image","image":{"ID":1752052,"id":1752052,"title":"Network Error Count","filename":"Network-Error-Count.png","filesize":14193,"url":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2022\/10\/Network-Error-Count.png","link":"https:\/\/www.esri.com\/arcgis-blog\/products\/utility-network\/electric-gas\/electric-creating-subnetworks\/network-error-count","alt":"","author":"304562","description":"Network Error Count","caption":"Network Error Count","name":"network-error-count","status":"inherit","uploaded_to":1751972,"date":"2022-10-28 12:48:29","modified":"2022-10-28 12:48:36","menu_order":0,"mime_type":"image\/png","type":"image","subtype":"png","icon":"https:\/\/www.esri.com\/arcgis-blog\/wp-includes\/images\/media\/default.png","width":384,"height":254,"sizes":{"thumbnail":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2022\/10\/Network-Error-Count-213x200.png","thumbnail-width":213,"thumbnail-height":200,"medium":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2022\/10\/Network-Error-Count.png","medium-width":384,"medium-height":254,"medium_large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2022\/10\/Network-Error-Count.png","medium_large-width":384,"medium_large-height":254,"large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2022\/10\/Network-Error-Count.png","large-width":384,"large-height":254,"1536x1536":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2022\/10\/Network-Error-Count.png","1536x1536-width":384,"1536x1536-height":254,"2048x2048":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2022\/10\/Network-Error-Count.png","2048x2048-width":384,"2048x2048-height":254,"card_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2022\/10\/Network-Error-Count.png","card_image-width":384,"card_image-height":254,"wide_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2022\/10\/Network-Error-Count.png","wide_image-width":384,"wide_image-height":254}},"image_position":"center","orientation":"horizontal","hyperlink":""},{"acf_fc_layout":"content","content":"\n
