ZH-8103 Embedded Power Quality Monitoring and Analysis Equipment

Detailed Product Description

ZH-8103 adopts advanced DSP, FPGA technology and embedded real-time operating system VxWorks. It can be applied to the place, where needs electricity quality on-line monitoring, such as transformer station, converter station, thermal power plant, hydropower station, electric railway, and research institutions, etc.

Function

1. Function of real-time online monitoring
   • It adopts trend chart, table, bar chart to monitor various index of power quality, which includes effective value, real effective value, power, and real power of fundamental wave of current and voltage, voltage and voltage deviation, system frequency and deviation, harmonic and inter-harmonic ratio and content, total harmonic distortion(THD), harmonic power, three-phase unbalance value, short time voltage flicker Pst and long time voltage flicker Plt.
2. Powerful function of signal processing
   • Power quality acquisition unit adopts high performance 32-bit DSP, which can monitor 64 channels data at most, frequency tracking technology and digital compensation algorithm, which has effectively eliminated frequency leakage and fence effect.
3. Based on VxWorks
   • It adopts embedded hardware and software, all the functions of power quality index calculation, off-limit triggering, data storage and communication are reached under VxWorks. The system is stable, reliable and real-time.
4. Function of rich spreadsheet
   • It will automatically create user-defined year month and day spreadsheet. It can lead out data of the selected time period to form a spreadsheet, which the content can be user-ordered and the format can be Word or HTML.
5. Function of off-limit alarming and protection tripping
   • When power quality is off-limit, it will alarm and record accordingly. The setting value of off-limit alarming and protection tripping can be set.
