Each switchboard group is an operationally
independent system, capable of monitoring and
controlling an associated generator.
switchboard is capable of distributing the power
produced by the associated generator to equipment
and zones fed by the switchboard bus. Operated in
parallel with either one or both of the other groups,
power can be supplied to the entire ship service load.
Power is produced by the generators, input to the
switchboards through the generator circuit breakers,
and distributed to the various ships loads via feeder
breakers and load centers.
Control and monitoring of the ships service power
is accomplished by the various manual, remote, and
automatic control functions associated with the
switchboards. In addition, the metering and
indications used to maintain proper power plant
performance give the electrician on watch the status
of the power plant at any given time.
The distribution system is protected from damage
by the various mechanical and electrical devices used
to interrupt the flow of electricity, either by command
or automatically, should a problem arise.
