The GF438R Rack-mounted power quality recorder is a high-end power quality monitoring device independently developed by GFUVE GROUP. It follows the national standard and international standard IEC 61000-4-30/IEC 61000-4-15/IEC 61000-4-7/IEEE 1459/EN 50160 etc for general requirements of power quality monitoring equipment and integrates multiple functions such as voltage and current sampling, harmonic analysis, fluctuation and flicker monitoring, unbalance monitoring, fault recording, event recording, and IEC61850 remote communication protocol.
DESCRIPTIONGF438R can measure multiple input signal parameters, including voltage RMS, current RMS, and phase angle; Harmonic content, effective value, phase angle; Interharmonic content and effective value; Voltage fluctuations and flicker; Voltage and current unbalance; Active power, reactive power, apparent power, power factor, harmonic power. GF438R has event recording function, which includes recording frequency deviation; Voltage and current effective value deviation; Voltage and current harmonics exceed the limit; Flashing beyond the limit; Unbalance exceeding the limit; Voltage rise, voltage drop, voltage interruption, surge current, etc.
GF438R device does not lose data during power outage and recovery, and there are no measurement errors at the moment of power outage; During the power restoration period, the monitoring device automatically returns to its working state before the power outage.

Monitor the 63rd harmonic component of the tested signal, including distortion rates of 1st to 63rd harmonics, total harmonic distortion rate, harmonic phase angle, and interharmonics, to meet the testing requirements of GB/T 14549 and IEC61000-4-7 for harmonics in public power grids.
■ harmonic analysis
The harmonic analysis function can analyze the harmonic, interharmonic, and high-order harmonic information of all user circuits, up to the 63rd harmonic. The content includes harmonic amplitude, phase, content, and other information such as THD value. You can freely choose to observe data in table or bar chart format.
■ Voltage fluctuations and fault recording
Capable of capturing waveforms of all voltage and current channels and analyzing interference sources. Harmonic components exceeding the standard, distortion rate exceeding the standard, voltage effective value exceeding the standard, short circuit faults, etc. can all initiate voltage waveform and fault recording to capture subtle changes in voltage waveform.
■ Component measurement and voltage unbalance analysis
It can measure the unbalance of voltage and current, as well as the amplitude and phase of zero sequence, positive sequence, and negative sequence, and display the phase diagram of voltage and current.
■ Record of steady-state events in power quality
The GF438R power quality recorder can continuously monitor steady-state events of power quality without interruption. Different triggering conditions can be set through software to start the statistics of excessive power parameters and record the corresponding superscalar, with a time resolution of 1ms.
■ Transient event recording of power quality
The GF438R power quality recorder can continuously monitor transient events of power quality without interruption. Different triggering conditions can be set through software to start the statistics of excessive power parameters and record the corresponding superscalar, with a time resolution of 1ms.
