The New Standard for
Power Management
The Signature System™ is
the most advanced
power quality monitoring system available on the market today. Able to
capture critical events that typically are missed by other systems, it
is completely web-based. Instead of proprietary software that must be
installed and updated on a PC, users only need a standard web browser
to access, view and analyze data. By logging onto a secure website,
multiple users can simultaneously view data in real time and from any
location. This shared-access feature allows users in various locations
to collaborate more effectively in making quick decisions on key power
quality and energy management issues. The affordable Signature System
is simple to learn, deploy and use, delivering immediate value to both
users and managers.
Modular and Flexible
The Signature System is a
multi-tiered power
quality analysis and energy management system. It is comprised of an
integrated system of DataNodes™, which are measurement and monitoring
instruments, InfoNodes™, the web-server and data analysis tool, and
where needed, enterprise software.
Distills Answers from
Raw Data
Key to the Signature
System are
AnswerModules™, a series of intelligent algorithms that convert raw
event signature data into precise answers for rapid and accurate
decision making. The Signature System is the only power monitoring
system to offer AnswerModules, which help users prevent and mitigate
equipment and process failure by pinpointing the location and root
cause of power disturbances.

Typical Applications
- Proactive
Management of Power Resources — The continuous capture of
all events enables users to develop trend lines and algorithms to
maintain real-time illustrations of infrastructure performance and
improve reliability, while automated alerting send alarms to power
managers before problems occur.
- Preventive and
Predictive Maintenance — Identifying pattern changes enables
better planning of maintenance activities and avoid interruptions of
critical business practices, while system data allows "just-in-time"
maintenance procedures to be developed and implemented.
- Reliability-based
Monitoring — The value and longevity of power conditioning
and mitigation equipment can be optimized by a reliability-based
monitoring approach using the Signature System.
- Early Detection
of Problems — Power quality problems can be detected before
they cause damage through benchmarking that sends alerts when
conditions begin to deteriorate.
- Implement Energy
Reduction and Cost Control Strategies — View and analyze
real-time energy demand and usage via the Internet. Trend and profile
that data to shift loads to off-peak hours, improve power factor or
reduce consumption.
- Allocate Costs
and Perform Activity-based Costing — Track energy-related
costs by department, tenant, process or output. Revenue-accurate
metering allows for easy cost comparison with utility bills.
- Manage Energy
Purchase Agreements — Use historical load profile data to
develop price/risk curves for evaluating energy purchase agreements or
for joining an aggregated group to purchase power at reduced costs.
- Perform Energy
Conservation and Load Reduction — Shed non-essential loads
or bring distributed generation on line to reduce consumption and/or
participate in utility-sponsored demand reduction programs. Evaluate
the value of energy efficient equipment such as lighting and HVAC
changes.
- Reduce Demand
Peaks and Related Costs — Avoid demand surcharges using the
Signature System to predict kW demand and identify the cause of demand
peaks and limit peak occurrences. Generate alarms on events such as
excessive load, equipment failure, or when operations are likely to
exceed contract terms for energy supply.
- Evaluate Impact
of Production Equipment on Energy Costs — Monitor the
efficiency of large, energy-consuming equipment to improve performance.
Plan for expansion by analyzing load trends and available capacity for
new equipment and tenants.
