Utility Network (ESRI)
Utility, Pipeline, and Telecommunications
 The utility network is the main component users will work with
when managing utility and telecom networks within ArcGIS.
 The common thread in these challenges is the network's
relationship to location.
Where are customers, sensors, meters, workers, and
waste? -- That's where GIS comes in.

Utility Network
 The utility network combined with a transaction model, attribute
rules, editing tools, and more allows users to completely model and
analyze their complex network systems for water, gas, electric,
telecom, sewer, stormwater, and other utilities.
 The capabilities to manage and analyze network data will be
delivered through the ArcGIS Utility Network Management
extension to ArcGIS Enterprise.
 The extension, which includes the utility network, provides the
ability to access all capabilities through a services-based
architecture callable from any device or application that supports
web services.

Utility Network….
 Knowing asset locations, their conditions, and their
relationship to one another is fundamental to managing them.
 But the GIS data was often kept from the people who needed it
most: field workers, executives, managers, service technicians,
and accountants.
 Limited resources and increasingly complex networks
Demands - Companies need a new wave of GIS-based
network management with more functionality, added
flexibility, and better access.
 The Utility Network lets users create, manage, and share
electric, water, wastewater, gas, district heating, and
telecommunications asset data.

Utility Network
 It is designed to model all of the components that make up your
system- such as wires, pipes, valves, zones, devices, and circuits and
allows you to build real world behavior into the features you model.
With the utility network you can:
 Create and edit features that model every type of utility equipment.
 Discover how features in the network are connected.
 Trace how resources, such as gas, water, and electricity, flow
through the network.
 Provide an operational view of how all the dynamic devices of your
utility are presently configured.
 Analyze how the network is affected by real world events like storms,
outages, or equipment failure.

Utility Network
 The utility network uses a services-based architecture which allows you
to share and collaborate on it everywhere.
 In command and dispatch centers, in design and engineering offices, on
desktop and mobile devices, in the office, and in the field.
 The utility network leverages the entire ArcGIS platform to create a
seamless GIS system that presents an accurate and unified view on the
status of your systems.
 This information can be served from your portal and be made readily
available on every device from desktop to smart phones.

Utility Network- Visualize your network

Utility Network- Visualize your network
The utility network offers a number of different ways to view
network system and assets:
 View thematic cartographic maps for different use cases, such as
customer service, field collection and inspection, or distribution
management.
 Create network diagrams that allow you to readily check
network connectivity and create logical views of your network
in a more simplified, symbolic representation of the information.
 View inside complex assemblies of devices and lines and
manage how assets are connected within them.
 Visualize a selected pressure zone or circuit with a display filter.
 Analyze your network

Utility Network- Analyze your network

Utility Network- Analyze your network
The utility network has an array of analysis and tracing tools to support a
large variety of analytic workflows:
 Perform inspection of the network in the aftermath of an event such as
a severe storm.
 Determine the number of customers with access to your resource. For
example, you can create a load summary report to present the number
of customers being fed by specific circuit in an electric network.
 Trace network features upstream or downstream from a given
location. For example, water utilities can determine which valves to
shut off when a pipe bursts.
 Model multiple utility systems within one utility network and run
tracing analysis across all of them. For example, an outage from an
electrical network can affect the delivery of another resource such as
gas or water. You can run a trace across all systems involved, see
where the problems lie, and decide on the best course of action.

Utility Network- Benefits of a utility network
 A utility network supports the requirements of utilities in delivering resources
to customers safely, reliably, and economically.
 It can serve as the system of record for the assets of a utility and provide
information about the present state of the utility system.
 Optimized for high performance and scalable to large utilities
 Models how components of your system are connected
 Represents dense areas of your system without map clutter
 Represents dense areas of your system without map clutter
 Enforces data integrity and reduces data entry errors
 Enables advanced analysis of your network
 Provides a comprehensive view of your network

Utility Network - Functionality
 Flexibility: Users can edit the network data seamlessly via web services.
 Asset connectivity: Users can mine the behavior of networks.
 For example, the technology can simulate the connection of a pipe to a valve or a
transformer to an electrical conductor.
 This can be done automatically by placing the network elements at the same
location or by specifying which objects are connected to each other.
 Containment: Users can place objects or devices within structures, such as
buildings or cabinets.
 For example, the Utility Network can show the internal electrical
connections of a substation inside the substation building or the internal
gas piping configuration within a gas meter station building.

Utility Network – Functionality…
 Attachment:
 Users can model network element attachments, such as how a
transformer or telephone cable is affixed to a pole.
 Quality:
 The technology leverages built-in, industry-standard rules that
guard against users making data entry mistakes.
 For example: Editors would not be allowed to connect a high-
voltage cable to a low-voltage one.
 Modeling:
 Users can specify where sources of electricity, gas, or water are
located to facilitate network simulation.
 They can also model devices that have many connection points,
such as complex switches and valves.

Utility Network – Advantages
Increased productivity:
 Users have access to shortcuts, templates, and streamlined workflows within
the software.
Tracing:
 The technology contains extensive, out-of-the-box tracing tools.
Visualization:
 The Utility Network supports 3D.
Schematics:
 It has an assortment of built-in network diagrams and one-line tools
(schematic representations of electric, water, and gas networks).
Workflows:
 The Utility Network helps users with editing, giving them guidance at every
step of the process.
 The technology continues to support the concept of long transactions as well,
which enable users to create future changes to the network model that go into
effect after a certain time.

Utility Network toolbox
• The Utility Network toolbox contains a number of tools that can be used to
create and manage the utility network layer, subnetworks, associations,
network topology, tracing, diagrams, and rules.
• Some of these tools can also be opened from the Utility Network tab as
described previously

Utility Network - Vocabulary
Asset group
 The asset group of a feature defines its broad classification.
 The ASSETGROUP field for each network feature class is defined as the
subtype field.
 Further classification of features is added by assigning attribute domains at
the subtype level on the ASSETTYPE field.
 A transformer is an asset group of a transformer in an electric device
network feature class.
Asset type
The asset type attribute of a feature defines a finer classification for each asset
group in a network layer.
 The ASSETTYPE field in a network layer is a text field linked to an
attribute domain of values.
 A power transformer is an asset type of a transformer in an electric device
network feature class.

Utility Network – Vocabulary..
Associations
Associations are created to associate features with one another.
 A connectivity association specifies that a transformer is connected to a fuse.
 A structural attachment association specifies that a capacitor is attached to a
pole.
 A containment association specifies that a vault can contain valves and pipes
Association rules
Association rules prevent an editor from adding logically invalid feature
associations in a network. Association rules define the valid ways network features
can be associated with each other.
 Connectivity rule: A transformer can connect to a fuse.
 Structural attachment rule: A capacitor can be attached to a pole.
 Containment rule: A vault can contain valves and pipes.

Connectivity
 Network features in a utility network can be connected to each other in two basic
ways: either with a shared endpoint, vertex, or point (common x-, y-, and z-
values), or with a defined connectivity association between two features that are
not spatially coincident. This is called connectivity.
 A pump placed at the end of a water pipe will have connectivity established
because of the shared location.
Connectivity association
 A connectivity association allows the individual features to be represented in the
network and establishes a connection between the network features that are
spatially disjointed. This is an integral part of performing tracing and analysis.
 A connection between a switch and a line is an example of connectivity
association.
 A connection between a fuse and an arrester that are not spatially coincident is
another example of a connectivity association

Container
 A container represents an assembly of network features that are normally shown
as a single feature on a map
 For example, an electrical switchgear container feature contains internal
switches, fuses, and a busbar, which are important for tracing analysis, but a map
showing all these internal features would be too dense. Network features inside a
container can be connected to features outside a container.
 Electrical substations and pumping stations are examples of container features.
Diagram view
 The diagram view shows a schematic view of your network.
 A diagram is a symbolic representation of features in a utility network with an
applied visualization technique.
 Diagrams can also show the results of a tracing analysis.
 At an electric utility, one type of diagram view is called a one-line diagram.

Utility Network - Structure network

Geometric coincidence
 When two or more features exist in the same x-, y-, and z-location, they are
geometrically coincident.
 Sometimes features can occupy the same x- and y-locations, such as devices
stacked on a pole.
 These features can be made to be not geometrically coincident by assigning z-
values.
Junction-edge connectivity rule
 A junction-edge connectivity rule is a type of connectivity rule that governs
which junction network features can be connected to endpoints or vertices of
line network features.
 A switch can be connected to the endpoint of a medium-voltage line.

Dirty areas
 Dirty areas mark modified features in a map that are out of date in the network
topology. Dirty areas are used as a visual cue to show which areas must be
validated to maintain the network topology.
 Dirty areas are cleared when the network topology is validated.
 A new medium-voltage line is constructed within the map and a new dirty area is
created that is visible around this feature.
Domain network
 A domain network is an industry-specific collection of feature classes such as
electric distribution or gas transmission.
 Sometimes a utility network will have two domain networks at the transmission
level and distribution level.
 A utility network can also have crossing domain networks, such as gas and
water, if they are both managed by that utility.

Map view
 The map view shows a cartographic display of your utility network.
 When edits are performed, dirty areas will appear on the map showing where the
network topology is not current.
Terminal
 Terminals model physical connections on a device. Not all devices require
terminals.
 Terminals are needed on a device type for three situations: when a device
transforms the resource (such as voltage or pressure) between the high side and
low side, when the flow of resource is asymmetric (such as a check valve), or
when there are three or more connections to a device.
 The use of terminals allows more realistic modeling of some devices and enables
more accurate data exchange to external analytic systems.
