CSP Transformers

CSP Transformers that contain fuses used without ADMS (Option 1)

Some transformer units include protective devices on either the primary side, secondary side, or both. A transformer may have a fuse in line with the primary winding, for example. If the customer is not implementing ADMS, the ArcFM UN recommendation is to map these attributes to the Asset Group Asset Type used when for a CSP type of Transformer; either RatedCurrent, MaxInterruptingAmps, or FuseLinkType. The transformer can be modeled as either in-line or tapped.

CSP Transformers that contain fuses and used with ADMS.

ADMS requires the fuse to be present for CSP Transformers. These fuses must be spatial. With this approach, a simple configuration technique can enable the GIS/ADMS integration infrastructure to map the GIS representation of a transformer with a contained fuse into the ADMS representation required to support the ADMS functions that depend upon the fuse data.

CSP Transformer requirement in ADMS

Required Configurations

• Use a spatial feature in the ElectricDevice feature class to represent the transformer.

• The transformer must in the E:Transformer – Inline category.

• The transformer unit records in the electric JunctionObject table must have an asset group and asset type that belong to the E:Transformer and E:Unit network categories.

• Use a separate spatial feature in the ElectricDevice feature class to represent the fuse.

• Junction-to-Junction connectivity cannot be used to connect the fuse to the primary line, or to the transformer. You must use a conductor connector. (Tip: If using Designer XI, the user can create a template that makes placing CSP Transformer easy).
