Transformer Network Categories

E:Transformer

Device

JunctionObject

Applies to all device asset groups and asset types that represent a transformer bank or all JunctionObject asset groups and asset types that represent a contained phase-associated unit (which may be a single-phase unit or a three-phase unit) of a transformer bank.

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 - Tap

Device

JunctionObject

Applies to all types within the transformer category that follow the tap connection style for transformers in the ArcFM UN electric model. This category may be used by editing tools.

E:Transformer - Inline

Device

JunctionObject

Applies to all types within the transformer category that follow the in-line connection style for transformers in the ArcFM UN electric model. This category may be used by editing tools.

E: Transformer - Three Winding

Device

JunctionObject

Sub-category of E:Transformer. Applies to all types within the transformer category that possess a tertiary winding. This category may be used by editing tools.

E:Transformer - Open Delta

Device

JunctionObject

Sub-category of E:Transformer. Applies to all device asset groups and asset types that represent an open delta transformer bank. This category may be useful for specifying conditions used by trace configurations and propagators in the UN, and it may also be used by applications that need to identify transformer banks that use the open delta connection pattern.

E:Transformer – Open Wye

Device

JunctionObject

Sub-category of E:Transformer. Applies to all device asset groups and asset types that represent an open delta transformer bank. This category may be useful for specifying conditions used by trace configurations and propagators in the UN, and it may also be used by applications that need to identify transformer banks that use the open wye connection pattern.

E:Has Connected Units (Unbalanced)

Device

The purpose of this category is to identify a type of device or conductor that requires units, in the bank/unit containment pattern, to carry phase-specific attributes and/or indicate continuity of a named phase through the device or conductor.

E:Has Disconnected Units (Balanced)

Device

Phase-Specific attributes carried at the device level only.

E:Overhead

Device

JunctionObject

Used to denote which transformers are installed on overhead poles

E:Underground

Device

JunctionObject

Used to denote which transformers are installed for underground equipment

E:Submersible

Device

JunctionObject

Used to denote which are designed for underwater connections

E:Unit

JunctionObject

Applies to all JunctionObjects that are contained within a bank that has the E:Has Connected Units or E:Has Disconnected Units category
