FeederInfo

FEEDERINFO is the model name of an optional 32-bit integer field that can be defined for any feature class belonging to the electric network. The FeederInfo field is used to store some extra results of circuit tracing operations by Feeder Manager. In particular, FeederInfo tells whether each phase is energized or not for a given feature, and, for line features, it also tells the direction in which the line was traversed (i.e., whether the edge’s from-junction or its to-junction was encountered first). As with the MMElectricTraceWeight, the individual bits of the FeederInfo integer value are interpreted to yield this information.

Description

31 - 14

Reserved

13

When this bit (called the SuperMultifeed flag) is set, it indicates the feature receives power from more than two circuit sources, which is more than can be named in the FeederID and FeederID2 fields. Feeder Manager 2 does not have this limitation and can list any realistic number of sources' names in its FeederIds field.

12

This bit, called the SubSource Multifeed flag, signifies whether the feature has more than one candidate for its ParentCircuitSourceID field. If the feature has no candidate or only one candidate for the ParentCircuitSourceID field, set the value to zero. If the feature has more than one candidate for the ParentCircuitSourceID field, set the value to one.

9

Represents any junction feature that serves as a tie device, i.e., an open device between two normally energized lines, which receive power from different sources.

8

Represents any junction feature that serves as a terminal device. This device, when open, prevents other features from being energized.

7

When this bit is set, it indicates the feature receives power from more than one circuit source.

6

When this bit is set, it indicates the feature belongs to an electrical loop (there is at least one circuit source that can reach the feature from more than one direction).

5 - 4

Reserved

3

Represents features that have no circuit source and cannot be energized.

2 - 0

Represent which phases are energized on the feature. A set bit means the phase is energized, an unset bit means it is not.
