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.
