Secondary Circuit Analysis is an electrical calculation (available in Designer) to easily perform "what-if" scenarios and determine which type of equipment will maximize the network's performance and minimize costs. Secondary Circuit Analysis helps designers calculate:

Secondary Circuit Analysis provides additional calculation options by:

The following tables must exist in your geodatabase (see Configuring Analysis Tools). Import them in Access, not ArcCatalog. For more information about how to use the sample tables provided, see Configure Analysis Tools.

To enable Secondary Circuit Analysis, assign model names as follows:

Configuring with a Denormalized Data Model

Secondary Circuit Analysis relies on a banked feature class with the model name TRANSFORMER assigned. On this feature class, it looks for a field with the field model name RATEDKVA assigned.

In your denormalized data model, you may have a Transformer feature class with multiple RatedKVA fields. Each of these fields may have a field model name similar to these: RATEDKVA_1, RATEDKVA_2, RATEDKVA_3. Secondary Circuit Analysis relies on one RatedkVA field. You must have a single RatedKVA field that sums the RatedKVA of the units. It must also carry the field model name RATEDKVA.
