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.
