6 InfraStruXure Power Generation System
How the InfraStruXure Power Generation
System Operates
Operation of the ATS during a utility failure when automatic operation is enabled
Your data center equipment
is typically powered by the
utility [Source 1] (
), while
the generator [Source 2]
remains off. When the level
of incoming utility power
falls below a specified
threshold (
), the ATS
signals the generator to start
(
). After the generator
starts and attains the
necessary power to support
the load, the ATS performs
an open transfer to the
generator (
).
The generator then continues
to support your data center
equipment (
) until an
acceptable flow of utility
power is restored (
). The
utility power must remain
stable for a specified length of time (Line Stable setting) and the generator must run for at least the
duration of its minimum run-time (Min on Gen setting) before the load will be retransferred to the
utility (
). The retransfer to the utility can be either open or closed. Following retransfer, the
generator cools down (
) and eventually stops.
