Perfect for Industrial, Commercial
and Utility Applications,
the "Performance Enhanced"
Nexus™ 1252 Meter is the newest
power meter in the industry-leading
Nexus ™series meters. The 1252
includes all the attributes of the
Nexus™ 1250 Meter as well as
a host of new features that arm users
with the highest level of PQ analysis
and communication on the market today
including:
- EN
50160 Flicker and Compliance Monitoring
- Interharmonic
Analysis
- DNP
3.0 Level 2 Plus Protocol
- Enhanced
Log Downloading
- Customized
Modbus Mappings
Compliant
with EN 50160 international standards,
the 1252 enables users to perform flicker
analysis
that can be damaging to both equipment
and humans. The unit provides you with
logging and monitoring for instantaneous
Short Term (PST-10 Min) and Long Term (PLT-4
hour) evaluation.
The
Nexus™ 1252 Meter's Log Viewer
program provides you with the ability
to do more comprehensive analysis
by viewing Interharmonics, the further
frequencies between the harmonics
of the power frequency voltage and
current which are not integers between
the fundamental.
Incorporating
the Industry leading, most advanced
DNP 3.0 Implementation Protocol (DNP
3.0 Level 2 Plus), the Nexus™
1252 Meter complies with all DNP Level
1 and Level 2 certification requirements
and additional key features including:

Technology
for both the Utility Power Quality
and Revenue Metering Departments
Historically, within a utility, separate
departments managed revenue metering
and power quality issues. Today, these
departments are merging. Metering
departments are providing additional
value to keep customers loyal to the
Power Utility. This also applies to
inter-ties between utilities. To meet
these applications, the Nexus™
1252 Meter combines the features of
a high-end revenue meter with advanced
power quality. The Nexus™ 1252
meter is the premier metering product
encompassing a technological quantum
leap.
Industrial and Institutional Users
Obtain High-End Power Quality and
Accurate Billing Measurements
Industrial and commercial customers
require "High- End" power quality
monitoring to record surges, sags
and transients within a facility.
Traditionally, expensive portable
power quality equipment accomplished
this task. With the Nexus™ 1252
Meter , the data is always available
online in the power meter to provide
the needed power quality assessment
immediately. Moreover, The meter's
precision accuracy can be used for
primary metering, sub-metering or
to check the installed utility meter.
