Voltage / Current Power Quality Analyzer
ARZ®-3L 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®-3L can
monitor and detect if the power quality fulfills IEC and EN
standard.ARZ®-3L fulfils all the important requirements of IEC 61000-4-30
Class A standard.
ARZ®-3L can work with our power quality monitoring and management
software to provide energy management solutions for enterprises.
With its strong networking capability, ARZ®-3L 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, and real time monitoring purpose.
