Handling Related Records for UN Migration

EddyClark

I found this text in the UN Migration Tools Documentation:

"Related records should be consistently managed; for example, if a fuse point on an electric network is protecting all three phases, the related record should have three-unit records, one for each phase. It should not be also represented as one-unit record with all three phases."

Is there an easy way to triple the amount of related records that I already have? 

Should the FuseUnit table specify which phase each unit is protecting?  i.e. [Phase] = B

Hi Eddy.

The document you are referring to is specifically for the FME for Electric Data migration to the Utility Network.  There are multiple migration tools and methods that can be employed which have different requirements.  One of the reasons the FME Workbench requires the Unit table is that these Unit records will be converted in to features (devices) and yes, one record per phase is required for devices like Transformers (Delta connected Transformers would have two phases), Fuses, Capacitors and Non-Gang operable switches.
