Type Asset:
•A generic asset used for planning and design purposes.
•For example a 50KVA Pole Top Transformer, a Class 2 Pole
•It is the basis for Compatible Units used for Design
•Whereas an AssetModel is a particular model and version of a vendor‘s
product, a TypeAsset is documentation for a generic asset or material
item.
•Any number of AssetModels may be used to perform this generic
function.
•The primary role of the TypeAsset is typically defined by the
PowereSystemResource it is associated with.

Asset
PowerSystemResource
Asset Model:
•A specific model and version made by a manufacturer (a type of
Organisation):
•For example a 50KVA Pole Top Transformer made by GE is a
separate AssetModel than 50KVA Pole Top Transformer made by
ABB
•Multiple AssetModels may be used to satisfy the procurement
requirements for a given TypeAsset. A single AssetModel may be
procured from multiple Suppliers (a type of Organisation)
•As construction or maintenance (replacement of a failed asset) is
scheduled for a given situation, price and availability primarily dictate
which AssetModel will be used.
•The primary role of the AssetModel is defined byTypeAsset, which is
typically defined by the PowereSystemResource it is associated with.

Asset:
•A tangible resource of the utility, including power system equipment,
cabinets, buildings, etc.
•The primary role of the Asset is typically defined by the
PowereSystemResource it is associated with.
•When inventory becomes to low for a given TypeAsset, a procurement is
made for a multiple assets for one AssetModel. One instance of Asset will
exists for every single physical asset procured:
•For example, 100 ABB 50KVA Pole Top Transformers are purchased
in one lot, each transformer with a unique serial number, location, etc.
•Construction and maintenance activities are performed against Assets,
not AssetModels or PowerSystemResources.

PowerSystemResource
PowerSystemResource:
•The role an asset plays in the operations.
•Operators operate PowerSystemResources, such as opening a switch,
without being directly concerned with the manufacturer of the switch, or
when it was installed.
•An asset such as a Switch can be replaced by another asset of the
same AssetType and it will not impact operations of the network (other
than while the switch is actually being changed).

TypeAssetCatalogue:
•Contain data for a set of utility asset types.
•It is a collection of information regarding generic types of assets that
may be used for design purposes, analysis, and so on.
•A TypeAsset is not associated with a particular manufacturer. .
TypeAssetCatalogue References:
•Only the identifier for the referenced data is to be included. The actual
data for referenced elements are provided through other types of
messages (e.g., AssetCatalogue):
•Can contain references to static reference data such as elements
of a AssetCatalogue.
•Leaf node elements such as Organisations.

Catalogue
PowerSystemResource
AssetCatalogue:
•A collection of information regarding available types of products and
materials that are used to build or install an Asset(s), to maintain an
Asset(s) or to operate an Asset(s).
•Each catalogue item is for a specific product available from a specific
supplier.
AssetCatalogue References:
•Only the identifier for the referenced data is to be included. The actual
data for referenced elements are provided through other types of
messages (e.g.,TypeAssetCatalogue):
•Can contain references to TypeAssetCatalogue elements or
Specifications .
•Leaf node elements such as Organisations.

List
PowerSystemResource
AssetList
•Can contain various amounts of data for any set of utility assets.
AssetList References:
•Only the identifier for the referenced data is to be included. The actual
data for referenced elements are provided through other types of
messages (e.g.,TypeAssetCatalogue, AssetCatalogue, NetworkDataSet,
Measurements):
•Can contain references to static reference data such as elements
of a AssetCatalogue or TypeAssetCatlogue.
•Can contain references to the types of PowerSystemResources
that specify the role in which the Asset is being used (i.e., if it has
been installed rather than sitting in inventory).
•Leaf node elements such as Organisations, Locations, and
Measurements.

PowerSystemResource
NetworkDataSet:
•Can contain data for any part of a distribution network typically selected for operational
or extension planning studies.
•The message contents could be part of a feeder, a single feeder or more than one
feeder.
•The data could be either the ‘As built’ network or a proposed network selected for
analysis.
NetworkDataSet References:
•Only the identifier for the referenced data is to be included. The actual data for
referenced elements are provided through other types of messages
(e.g.,TypeAssetCatalogue, AssetCatalogue, AssetList, Measurements).
•To other Documents containing static reference data such as TypeAssetCatalogue
or AssetCatalogue.
•To Assets performing the roles of the associated types of PowerSystemResources.
•For other “leaf node” elements such as Organisations, Locations, and
Measurements.
