General
Power quality monitor APView400 integrates a high-performance multi-core platform and an embedded operating system, and monitors power quality indexes stipulated in IEC61000-4-30 testing and measurement techniques - power quality measurement methods, and provides various functions such as harmonic analysis, waveform sampling, voltage dips/swells/interruptions monitoring, flicker monitoring, voltage unbalance monitoring, event recording and measurement control.
It meets IEC 61000-4-30 Class A Edition 3.1 with respect to standardization of power quality index measurement methods, measurement accuracy of index parameters, clock synchronization, event alarms and others and satisfy the demands of power quality monitoring of power supply system up to 110kV.
Therefore, it is widely applicable for power quality monitoring in chemical industry, steel industry, metallurgy industry, hospitals, data centers, transportation, construction industry and other industries.
