Represent Conductor Paths Correctly

A single conductor in the electric network may represent up to three phase conductor paths, plus an optional neutral path. The phase paths present for a conductor are indicated with the PhasesNormal attribute where at least one physical phase conductor is assumed to be present for each of the phases named in this attribute. The neutral path for a conductor (if present) is indicated with the NeutralType attribute. At least one physical neutral conductor is assumed to be present, based on the NeutralType attribute information.

One example is when utilities upgrade the capacity of a circuit by adding phase conductors in parallel to already-existing phase conductors and each of those conductive paths can have one or more physical lengths of conductor running in parallel.

The conductor can represent many physical conductors, where each one can be a different size or material from the others, belong to a named phase, or belong to the neutral conductive path.

Coincident Geometry vs Junction-to-Junction Connectivity

​The Esri UN allows spatial features to use junction-to-junction connectivity instead of a geographic coincident. The ArcFM UN electric model strongly discourages the use of Junction-to-Junction connectivity to connect two features that have point geometry because it does not work well with ADMS and some ArcFM applications, such as Designer XI.

Exception to this rule

• Junction-to-Junction association used to join the tap transformer to its tap junction.

• Internal connections of a Vault to the EdgeConnector that ends a non-spatial conductor in Conduit Manager. For more information, see the Editor XI Conduit Manager Data Model article.

  ​We recommend adding a Network Category, such as E:Connector Conductor, to note a conductor that represents devices as in-line.

  

Conductor Modeling with ConductorInfo Records

​If a customer intends to have conductor info records in the ElectricEdgeObject table, the conductor represented in the ElectricLine feature class should have its Asset Group Asset Type assigned to the E:Has Conductor Info network category. The presence of the network category requires the feature to have conductor info records in the ElectricEdgeObject table. Do not use this network category ​If you do not intend to have conductor info records for a particular Asset Group Asset Type.

Required Configuration

• ​A conductor feature Asset Group Asset Type must belong to the E:Has Conductor Info category to have conductor info records.
