Phases Normal Attribute

The PhasesNormal attribute identifies the named electrical phases A, B, and C that are present and operational for each object in the ArcFM Utility Network (UN) electric model. The phase names can be customized with a coded value domain in the UN so that a different letter or word is used for each of the three phases. Some distribution utilities use the phase names R, Y, and B where others may use L1, L2, and L3. This attribute is present on every feature and object in both the balanced and the unbalanced electric models. The PhasesNormal attribute is a short or long integer field that is designated as a network attribute in the UN. Make sure the least significant three bits are declared as in-line bits in the UN’s in-line attribute bit-space and represents one of the named electrical phases.

Required Configuration

• The PhaseNormal attribute must be added to all Electric Domain Network feature classes and Domain Network object classes to support the ArcFM UN.

• The value coded domain for the PhasesNormal attribute should be configured as shown in this table.

  The domain assigned to the PhasesNormal field differs from the domain used by the EnergizedPhases field, since the proper interpretation of the value zero is different between those two fields.
