Circuit Segments Overview
This subsystem contains classes and properties that describe the conductors that transmit and distribute electric current. Circuit segments can be categorized as simple or complex edges and objects. The inherent behavior of complex edges is very different in ArcGIS Electric Distribution than the traditional ArcInfo topology model. The ArcGIS Electric Distribution system automatically maintains the relationships between complex edges, any attached devices, and other edges so you can choose how you want to physically segment your network. For instance, it makes sense to physically segment electric lines between fuses and switches since, among other things, it is important to keep circuit data on lines, depending on which side of the fuse they are on.
For example, if you place a fuse on an overhead primary that originally was associated with CircuitID 001, it may be that the overhead primary west of the fuse is part of CircuitID 001, but the overhead primary east of the fuse is now associated with CircuitID 005. At the same time, it is not necessary to physically segment electric line segments at splices.
Once your network is in place and you move an electric line segment, any attached switches, fuses, transformers, and other portions of the network automatically move with it. ArcFM™ determines whether a complex edge should be split based on the type of junction (device) being added. As with most of the subsystems discussed in this document, a common set of properties is defined in a top-level abstract class. All subclasses beneath the abstract class ElectricComplexEdge inherit these properties.
