Features:
APView series power quality on-line monitoring device uses a high-performance multi-core platform and embedded operating system, in accordance with the IEC61000-4-30 "Test and measurement technology - Power quality measurement methods" specified in the power quality indicators of the measurement method. It integrates harmonic analysis, waveform sampling, voltage sag/sag/interrupt, flicker monitoring, voltage unbalance monitoring, event recording, measurement and control control and other functions, which can meet the requirements of power quality monitoring of 110kV and below power supply systems.Scope of application:
Widely used in chemical, steel, metallurgy, semiconductor, hospital, data center, transportation construction, new energy and other industries power quality monitoring.
Remark 1: In the table, U_N is the nominal voltage and I_N is the nominal current.
Note 2: U_h is the actual test value of the HTH (intermediate) harmonic voltage; U_hN is the given value of the HTH (intermediate) harmonic voltage.
Note 3: I_h is the actual measured value of the HTH (intermediate) harmonic current; I_hN is the given value of the HTH (intermediate) harmonic current.
