Product Description
16 Relay LCD 127th Power Quality Testing / Signal Source Analyzer 50 / 60 Hz
Product Profile
ARZ®-3W power quality analyzer is an integrated monitoring, analyzing and controlling device that offers electrical parameter metering, harmonics metering and analysis, waveform sampling, measurement of Voltage swell, dip, interrupt, Voltage unbalanced ratio, demand, fault record, event record, data record. ARZ®-3W can monitor and detect if the power quality fulfills IEC and EN standard.
ARZ®-3W fulfils all the important requirements of IEC 61000-4-30 Class A standard.ARZ®-3W can work with our power quality monitoring and management software to provide energy management solutions for enterprises. With its strong networking capability, ARZ®-3W can display and record all the data records on the interactive trend chart. A data report can be formed periodically. The report can be used for fault analysis, statistics, real time monitoring purpose.
Application
>Power quality detection and management
>Disturbance analysis, faults analysis, device pre-maintenance
>Long term record and analysis
>Power loads analysis
>Energy consumption evaluation and analysis
>Utilizing GPS synchronization to analyze the relevance between events in different locations
>Applied scope: Single phase and 3phase electrical power system
