During normal operation CB1 is closed and
CB2 open. Switchboard S2 is fed by the
transformer. If the main source is lost, the
following steps are carried out:
1. The mains/standby changeover switch is
operated and CB1 is tripped.
2. Load shedding if necessary of part of the
loads on the priority circuit in order to limit the
load impact on the generator.
3. Start-up of the generator.
4. CB2 is closed when the frequency and
voltage of the generator are within the
required
ranges.
5. Reloading of loads which may have been
shed during step 2.
Once the main source has been restored, the
mains/standby changeover device switches
the S2 supply to the mains and the generator
is stopped.
