Utility Network

A feature dataset in an enterprise geodatabase that models utility systems with devices, junctions, lines, and associations, enabling tracing and analysis. It requires branch versioning and network topology.

Device

A point feature in the utility network that can have terminals and represents equipment like transformers or switches. Devices can be connected to lines and participate in traces.

Junction

A point feature without terminals that represents a connection point, such as a valve or service point. Junctions connect to lines and are part of the network topology.

Line

A polyline feature that represents a linear asset like a pipe or cable. Lines connect devices and junctions and can have edge objects for non-spatial connectivity.

Terminal

A connection point on a device that defines where lines can connect. Devices can have up to eight terminals, and terminal configurations define internal connectivity.

Subnetwork

A collection of features sharing a common network characteristic, defined by a subnetwork controller. Subnetworks are used for tracing and analysis, such as pressure zones.

Tier

A network hierarchy level assigned to subnetwork controllers that determines trace behavior. Tiers have ranks and trace configurations for hierarchical analysis.

Association

A non-spatial relationship between features, such as connectivity (junction to edge) or containment (transformer bank containing transformers). Associations are stored in the network topology.

Attribute Rule

A geodatabase rule that enforces data integrity through calculation, constraint, or validation. Attribute rules are evaluated during editing and can be batch-calculated.

Network Topology

A set of tables storing connectivity and associations for the utility network. It must be enabled and validated after edits to ensure accurate tracing.

Create Utility Network

A geoprocessing tool that creates a utility network in a feature dataset. It adds system tables and fields, enables branch versioning, and builds the network topology.

Asset Type

A specific category of asset within an asset group, such as 'Single-phase overhead transformer'. Asset types define terminal configurations and connectivity rules.

Asset Group

A broader classification of assets, such as 'Transformer' or 'Switch'. Asset groups contain asset types and are used to organize network features.

Terminal Configuration

A configuration per asset type that defines the number of terminals and internal connectivity. For example, a transformer may have source and load terminals connected internally.

Subnetwork Controller

A device or junction with a subnetwork controller asset type that defines a subnetwork. Controllers are assigned to tiers and manage subnetwork updates.

Connectivity Rule

A rule that defines which asset types can connect to each other, such as line to transformer. Connectivity rules are enforced during editing and topology validation.

Network Attribute

A property assigned to feature classes, such as phasemodel or pressure, used in traces. Network attributes can be numeric or bitwise and are configured in the utility network properties.

Branch Versioning

A versioning model required for utility networks that allows multiple users to edit named versions. Edits are saved to versions and reconciled/posted to the default version.

Validate Network Topology

A tool or operation that updates the network topology after edits, ensuring connectivity and associations are correct. It must be run before tracing.

Create Association

A tool used to create connectivity or containment associations between features. Associations are stored in the network topology and are validated during editing.

Error Inspector

A pane in ArcGIS Pro that displays errors from attribute rules and connectivity rules during editing. It allows inspection and correction of invalid features.

Update Subnetwork

A tool that refreshes subnetwork names and traces after edits. It updates the subnetwork controller's subnetwork and ensures trace results are current.

Batch Calculation

The process of running attribute rules on a selection or entire feature class using the Calculate Attribute Rules tool. It is used to populate fields for existing data.

Reconcile and Post

The process of merging edits from a named version into the default version. Reconcile detects conflicts, and post applies changes to the default version.

Trace Types

The categories of traces in the utility network, including Connected, Upstream, Downstream, Loops, Shortest Path, Subnetwork, Isolation, and Protective Device.

Trace Configuration

Settings that control a trace, such as traversability, include containers, include barriers, and output options. It determines which features are returned.

Upstream Trace

A trace that finds features upstream of a starting point based on flow direction or subnetwork controller. It is used to identify sources or feeders.

Downstream Trace

A trace that finds features downstream of a starting point. It is used to identify customers or assets affected by a change.

Subnetwork Trace

A trace that returns all features in the subnetwork containing the starting point. It requires a subnetwork controller and uses the tier's trace configuration.

Isolation Trace

A trace that identifies the section of the network that can be isolated by protective devices. It requires protective devices to be configured and is used for outage planning.

Trace Locations

A pane in ArcGIS Pro that manages starting points and barriers for traces. Barriers stop the trace at specified features.

Publish Utility Network

The process of sharing a utility network feature dataset as a feature service with the Utility Network capability enabled. It requires ArcGIS Enterprise and branch versioning.

Service Administration

Managing the utility network feature service through ArcGIS Server Manager or ArcGIS Pro, including capabilities, version management, and stopping/starting the service.
