Propagators and Phases Energized Field

[YulissaCamacho]

Hi. We have been working in the connectivity of an Electric Utility Network and a couple of questions pop up: 

We're trying to implement propagators to phases but not quite understand the function Bitwise And. Anyone have like a use case or something like that?

The second question is the impact that the field phases energized have in the network connectivity. This because we found a case where four lines with different phases cross each other and if the Three Phase ones don't have in the Phases Energized the phases that the other lines have the subnetwork don't pass.

This article depicts how the bitwise and operator is used to manage phasing. It is also discussed in this presentation from last year's Esri User Conference.

The second issue you asked about is also described in that presentation. To summarize: If a feature is expecting a specific set of phases and NONE of those phases make it to that feature, it will not be part of the subnetwork and its phases energized will be set to de-energized. If at least one of the expected phases makes it to the feature it will be energized and part of the subnetwork, but the phases energized will be less than the expected phases.

Thank you for the quick answer. 

About the second issue, leaving behind the propagator functionality, If I do not have that operator active... The phases energized field can make that a part of the subnetwork stays deenergized? Because I understand that network attributes like LifeCycleStatus or DeviceStatus or phasespassedthrough can control the subnetwork but, the values of the phases energized field impact too?

Yes, propagation affects traversability in a way similar to condition barriers like lifecycle and device status. When the function that propagates values returns false for a feature, the trace will stop at that feature and not include it in the network.
