Course Objectives
Participants will be able to:
 Identify common paralleling topologies, plus their advantages and
disadvantages, so they can make informed choices in paralleling system
design.
 Recognize effects of system topology on maintainability and scalability so
they can consider these factors in system design.
 Describe Uptime Institute Tier Ratings and their implications on generator
sets and power distribution systems.

LOAD 2
 Load control required to make sure that sufficient capacity is on line before
connecting loads
 Each generator set must be large enough to carry emergency loads
– Need to be on line in 10 seconds (NFPA 110)

Isolated Bus with Gen Main
 Minimum generator sets online
before connecting critical load

Uptime Institute Tier Ratings
PowerHour
Tier Level Ratings
 The tier rating system is the industry standard
for benchmarking data center reliability.
 Four tiers, each building on requirement to the
one below (ex. Tier II requires all of Tier I
capability, plus the added requirements).
 Power Generation and distribution is one of 16
subsystems evaluated.
 No fractional tier ratings.
 Tiers do not specify certain equipment, but
rather a level of redundancy and security to
maximize run time.
 To be an enterprise class data center, UPS
and generator sets are required equipment.
 Significant costs associated with higher tier
rating.

Tier III: Concurrent Maintainability
 Adds redundancy to network distribution paths as well as
capacity established in Tier II systems.
 Every distribution component can be removed or replaced during
a planned event without loss of service.
– Allows for a more proactive maintenance program
– Enables site to be upgraded as technology, capacity and infrastructure
requirements change
 An unplanned event can still lead to disruption.

Generator Sets for Tier III or Tier IV Systems
 “Disruptions to the utility power are not considered a failure but an
operational condition for which the site must be prepared”
 “A Tier III or Tier IV engine-generator system, along with its power paths
and other supporting elements shall meet … performance confirmation tests
while they are carrying the site on engine-generator power”
 “Engine-generators for Tier III and Tier IV sites shall not have a limitation on
consecutive hours of operation when loaded to ‘N’ demand”

defined as:
The maximum power which the generator is capable
of delivering continuously to a constant or varying
electrical load for unlimited hours in a data center
application.
PowerHour

PowerHour
Integrated Monitoring Sensors
Sensors that are integrated and connected to the generator
set control are critical to providing advanced notification of a
maintenance or service need.
Examples
 Air cleaner restriction indicators
 Exhaust port temperature
 Alternator bearing and RTD
PowerHour
Cooling System
 Factory designed, validated and supplied cooling systems capable
of 40C and 50C ambient temperatures are critical when it comes to
providing the performance and reliability that data center customers
demand.

PowerHour
Summary
 Using standard system topologies makes the system
more reliable and serviceable.
 Consider ease of maintenance and future expansion
when designing system topology.
 The Uptime Institute Tier Rating system serves as a
good framework for evaluating redundancy,
maintainability and scalability in a system design.
PowerHour
