Equipment Network Categories

Equipment type categories are used to identify electrical equipment with respect to its basic function, such as a transformer, switch or conductor. They are also used to identify meaningful subclasses within some equipment types. Membership in an equipment type category often implies a set of applicable attributes. For example, the transformer category feature in a Utility Network (UN) is expected to have a PrimaryConnectionType attribute.

Required Configuration

All categories that apply to any given AssetGroup AssetType combination, both general and specific, should be assigned to that combination. This means that a combination for a fuse type in the device table, should belong to all of the categories shown for this example:

Example - Category assignment for an AssetGroup/AssetType combination in the Device table that corresponds to "fuse"

E:Switch
E:Switch - Fuse
E:Protective

NOTE: For equipment types in the unbalanced model, both the bank and unit will have the same network categories applied to them, differing only by the E:Has Connected Units (bank only) and the E:Unit (unit only) categories.

Network Category Name	Applicable tables	Description
E:Busbar	Line EdgeObject	Applies to features in the Electric Line feature class that model busbars. These features must have fields that carry phase and voltage.
E:Conductor	Line EdgeObject	Applies to line features that represent conductors. These features must be in the Electric Line feature class and must have fields that carry phase and voltage.

E:Fault Indicating	Device	Applies to a feature or object in the Electric Device table that represents devices or sensors that indicate where faults are occurring.
E:Lightning Arresting	Device	Applies to a feature or object in the Electric Device feature class that represents lightning protection equipment.
E:Power Factor Correcting	Device JunctionObject	Applies to a feature or object in the Electric Device feature class that compensates for fluctuations in available power and reduces inefficient energy consumption.

E:Power Factor Correcting - Reactor	Device JunctionObject	Sub-category of E:Power Factor Correcting
E:Riser	Junction	Applies to a feature in the electric junction table that represents a junction at the location where a span conductor travels from underground to overhead (or vice versa).
E:Service Point	Device JunctionObject	Applies to a feature or object in the electric device or electric junction object table that represents a service point or meter.
E: Critical	Device JunctionObject	Applies to a feature or object in the electric device or electric junction object table that represents a critical service point in which supply to power must not be interrupted.
E:Primary	Device JunctionObject	Applies to a feature or object in the electric device or electric junction object table that represents a service point that is energized from the primary circuit.
E:Secondary	Device JunctionObject	Applies to a feature or object in the electric device or electric junction object table that represents a service point that is energized from secondaries.
E:Streetlight	Device	Applies to a feature or object in the Electric Device feature class that represents streetlights.
E:Switch	Device JunctionObject	Denotes the main feature or object (as opposed to a unit) that represents a switch bank or device.
E:Switch - Circuit Breaker	Device JunctionObject	Sub-category of E:Switch.
E:Switch - Disconnect	Device JunctionObject	Sub-category of E:Switch.
E:Switch - Fuse	Device JunctionObject	Sub-category of E:Switch.
E:Switch - Load Break	Device JunctionObject	Sub-category of E:Switch.
E:Switch - Reclosing	Device JunctionObject	Sub-category of E:Switch.
E:Switch - Sectionalizing	Device JunctionObject	Sub-category of E:Switch.
E:Device Controller	JunctionObject	Applies to a JunctionObject record that can be contained by another JunctionObject record representing the unit has a device controller.
E:Transformer	Device JunctionObject	Applies to a feature or object that represents a transformer bank (this includes a single-phase transformer device, which is modeled as a bank that contains only one unit.
E:Transformer - Step	Device JunctionObject	Sub-category of E:Transformer. Applies to a feature or object in the Transformer category whose primary and secondary voltages are in the same general voltage class (typically both MV).
E:Transformer - Open Delta	Device JunctionObject	Sub-category of E:Transformer. Applies to a feature or object in the Transformer category whose windings are connected in the open delta pattern. Can be referenced by conditions in trace configurations for any tracing applications that need to give special treatment to open delta transformers.
E:Transformer - Open Wye	Device JunctionObject	Sub-category of E:Transformer. Applies to a feature or object in the Transformer category whose windings are connected in the open wye pattern. Can be referenced by Conditions in Trace Configurations for any tracing applications that need to give special treatment to open wye transformers.
E:Transformer - Three Winding	Device JunctionObject	Sub-category of E:Transformer. Applies to a feature or object in the transformer category that has 3 windings.
