To Classify Devices

To manage Electric meta tables

1. In the Infrastructure Administrator, do one of the following:
   • Click Enterprise and connect to the enterprise industry model . Open a project.
   • Click File and open an industry model drawing or template.
2. Open an Electric NA or CE workspace.
3. In the tree view, click the node for the electric industry model to modify.
4. Click Industry Model menu Electric.
5. Click the Meta Tables tab.
6. On the Meta Tables tab, under Device Class, specify the device type for each device feature class.

Meta Tables	Description
Device Class	Displays the device feature classes that are part of the Electric topology. See Electric Device Types. Device types classify a device as load, switchable, protective or feeder. Several analysis workflows use the device type, such as Find Feeders, Finding Fed Devices, and Find Alternative Supply.
Device Type	Specifies the device type. Feeder: A switchable device that can act as the starting feature for a circuit or can separate circuits. Protective: A switchable device that can operate on its own. Switchable: A switchable device that can interrupt current. Load: A load device or termination point. Conductor: Note, this type is included for completeness but conductors are the only features of this type.
Voltage Attribute	Displays all feature classes that have a relation the to the domain table EL_VOLTAGE_TBD. Feature classes can have multiple voltage attributes. These are provided in the drop down list. Voltage attributes are used by some Electric feature rules. For example, when a new feature is connected to the electrical topology, the voltage of the existing feature is propagated to the new feature. Some devices such as transformers have a primary voltage attribute and a secondary voltage attribute.
Voltage Attribute	Specifies the primary voltage attribute.
Secondary Voltage Attribute	Specifies the secondary attribute. For example, a transformer has a primary voltage and a secondary output voltage.
