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, Nexus combines the features of a high-end revenue meter with advanced power quality. Nexus 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 Nexus, the data is always available on-line in the power meter to provide the needed power quality assessment immediately. Moreover, Nexus' precision accuracy can be used for primary metering, sub-metering or to check the installed utility meter.
User Defined Expandable I/O, RTU and Trending Functions Customize Nexus for Every Application
Nexus offers virtually unlimited I/O capability in conjunction with all metering functions. Using the expandable I/O allows the meter to be used for every metering and data gathering application. Nexus' modular plug and play modules allow you to add Analog and Digital I/O to specifically meet your application. You will no longer need PLCs or RTUs to accomplish these tasks.
A portable version of the Nexus is avilable as well
