EATON CORPORATION %NERGY-ANAGEMENT3YSTEM
The architecture of the
monitoring system is
straightforward, which makes
it stable and reliable. Branch
circuit wires are threaded
through current transducers
(CTs), which sense the current
level going through the wire
and send the information to
a universal controller. CTs are
also used for sub-feed and
main breakers. The controller
assimilates the information from
CTs at multiple panelboards and
then relays it to a local display
or remote management system
for analysis and reporting. The
CTs are exceptionally robust
and have a very long life
expectancy.
A single system can expand
up to six 42-circuit panelboards
(up to 252 pole positions or 20
three-pole sub-feeds depending
on PDU configuration), in
addition to monitoring the main
input/output parameters of the
distribution equipment, such as
a power distribution unit (PDU)
or remote power panel (RPP).
Detailed insights into
circuit-level power
conditions
The Energy Management
System assesses circuit
activity 24/7 and provides time-
stamped metering along with
alarm and statistical information
for each branch circuit. You
get the significant information
necessary to effectively
manage the edge of the power
distribution system.
For example, you can see
minimum and maximum
current, power, and frequency;
power quality metrics such
as total harmonic distortion
and power factor; time-
stamped event records;
and more. This information
is shown for individual
circuits and summarized for
each panelboard and at the
equipment level, such as PDU
or RPP. You get visibility at all
levels within one unit.
Early warning of problem
conditions
When current on a branch
circuit or main circuit breaker
reaches a user-defined
threshold, the system sends
a warning alarm to the local
display and the defined
communications network,
identifying the specific circuit
and the condition. The data
center or facility manager is
alerted, with time-stamped
information, before the current
approaches the breaker’s trip
point.
Local and remote access to
power monitoring data
Most other monitoring systems
on the market require you to
purchase a separate display if
you want to view circuit activity
and alarms locally or can’t
review an entire system in a
single display.
With this system, a state-of-the-
art multi-line LCD local display
is included in the base system
package. Technicians always
have an up-to-the-minute view
of power conditions right at the
equipment.
With an optional Power Xpert
Gateway 1000 interface
card the universal controller
sends data to your building
management system or power
management system (such
as Eaton PowerVision
®
or
FORESEER
®
systems) using
industry-standard Modbus and
Web/SNMP protocols.
Monitoring of
environmental conditions
In addition to readings of
electrical activity, the Energy
Management System monitors
key environmental conditions,
such as temperature and
humidity of the distribution
equipment. For a PDU, the
system can measure the
temperature of the unit’s
transformer. These capabilities
enable data center managers to
identify trouble conditions and
then design layouts that avoid
undesirable hot spots.
The Eaton Energy
Management System
sends data from up to six
panelboards, up to 252
pole positions, to a single
display— and sends warning
alarms if conditions could
potentially trip any branch
or main circuit breaker.
