7.1.3 Busbar sections
The power management system manages the power for the busbar sections, according to a set of power management rules. If bus
tie breakers are present, then the busbar sections are dynamic. That is, the sections change whenever bus tie breakers are opened
or closed.
Each BUS TIE breaker controller and each externally controlled bus tie breaker can create a new busbar section, as shown in the
example below.

in this document for
information about setting up and controlling an externally controlled bus tie breaker.
When the breaker(s) are open, each busbar section is independent from the other section(s). The controllers in the section manage
the power independently for that section.
If the breaker(s) are closed, then the connected busbar sections together form one busbar section, as shown in the example below.
The controllers in the connected busbar section manage the power for the combined busbar section.
