Distribution Tracing

Hi Team,

I am setting up the subnetwork in the Distribution Tier and assigned Circuit Breaker as controller

And on both the end, MV Bus bar is connected , when I update the subnetwork and check the bus bar that is being a part of the subnetwork

When I checked the Rules , The Bus bar's only connect to Bus side of the Circuit Breakers . Because In our substation all of the connectivity is based on the bus bar. How do we tackle this ?

Can we add a rule to connect the bus bar to the line side of Breakers?

@KokilaM

This is the issue I was describing in our previous thread about why your circuits weren't tracing properly. You need to add a second rule that allows busbar to connect to the line side of a circuit breaker as well, then connect the busbar that goes into the field to the line side terminal.

This is one of the reasons why customers, and the newest model, have separate classifications for circuit breakers that are subnetwork controllers versus circuit breakers. The terminal configuration on non-controller circuit breaker (if you use one) should also be defined to be bi-directional so it doesn't restrict the direction of flow of electricity within the substation when backfeeding or switching sources.

If both lines are connected to the terminal, then the trace will bypass the device (regardless of whether its open or closed) and if there is a subnetwork controller on the line side terminal of the breaker it will not propagate.
