Function Introduction:
The basic parameters of the instrument can measure three-phase voltage, harmonic and sequence components of three-phase current, voltage fluctuations and flickers, voltage deviation, power factor, active, reactive, and frequency.
       Power quality monitoringThe parameters can measure three-phase fundamental voltage, three-phase fundamental current, three-phase fundamental active and reactive power, positive sequence negative sequence zero sequence voltage, positive sequence negative sequence zero sequence current, three-phase voltage fluctuation, short-term flicker (Pst), long-term flicker (Plt) Δ S fluctuating load apparent power variation, three-phase voltage imbalance, harmonic measurement (50 times, level A), three-phase harmonic voltage content, three-phase harmonic current content, three-phase harmonic active and reactive power, three-phase voltage harmonic distortion rate, and three-phase current harmonic distortion rate. Automatically generate a report file on exceeding the limit every day, recording the start and end times of each harmonic exceeding the limit and the values at the time of exceeding the limit on a large LCD screen. It can display real-time power quality parameters such as three-phase voltage, current effective value, and 00-50 harmonics. Provide instrument crash self recovery function. Transient voltage (including voltage surge, voltage drop, overvoltage, undervoltage recording). Background software function Site management function: including site information setting and channel information setting functions, which can set, modify, and edit the basic information and detailed information of the site and channel, including transformer ratio setting, wiring mode setting, user mode setting, voltage and current harmonic limit setting, and other power quality indicator limit settings. Data analysis function: Data analysis is the core content of this monitoring system. It is responsible for statistical analysis of real-time or historical data of multiple power quality indicators collected by the device, and forms various reports, curves, pie charts, and bar charts. The statistical analysis results can be exported to various formats such as RTF documents, EXCLE tables, HTML files, PDF files, text files, JPG image files, etc, It also supports printing, editing, and output functions. Transient event recording: The system can record transient events such as voltage surges, voltage dips, overvoltage, undervoltage, etc. during a selected time period, including transient data recording, transient event list recording, and transient event result analysis. At the same time, it supports the printing and output of transient event records. The system can provide annual reports, quarterly reports, and The monthly report and any time period statistical report printing and output function, the report statistics content includes the maximum, minimum, average, 95% probability value, national standard limit value, and qualified judgment of the 00-25th harmonic voltage and current of three-phase A, B, and C, respectively; Voltage deviation, short-term voltage flicker, long-term voltage flicker, voltage imbalance, current imbalance, frequency and deviation, active and reactive power, as well as the maximum, minimum, average, 95% probability value, national standard limit value, and judgment of whether the true power factor and displacement power factor of A, B, and C three-phase are qualified. All content is displayed on 7 pages. Simultaneously supports exporting statistical reports as RTF documents, EXCLE tables, HTML files, and PDFs
