Common Features

Harmonic Analysis

Monitor the 2-63rd harmonic components of the measured signal, including the distortion rates of the 2-63rd harmonics in three-phase voltage, three-phase current, inter-harmonics between three-phase voltages, inter-harmonics between three-phase currents, total harmonic distortion rate of three-phase voltage, and total harmonic distortion rate of three-phase current. Complies with the testing requirements for public grid harmonics as specified in national standard GB/T14549-1993.Voltage Fluctuations, Flicker, and Fault Wave Recording

The online power quality monitoring device can capture waveforms of all voltage channels exceeding the limit. Overvoltage, short-circuit faults, and other issues can trigger voltage transient waveform recording, thereby capturing subtle changes in voltage waveforms.Quantity measurement, voltage unbalance, and deviation analysis

The online power quality monitor can measure the unbalance degree of voltage and current, as well as the amplitudes of zero sequence, positive sequence, and negative sequence, voltage deviation, and display the phase diagram of voltage and current.Power System Monitoring, Alarm, and Recording

Multiple data monitoring, alarm, and recording, including frequency limit alarm, three-phase voltage harmonic alarm, three-phase current harmonic alarm, voltage out-of-range alarm, total voltage distortion rate alarm, and voltage unbalance alarm, along with real-time monitoring and recording of various parameters.

Power Quality Monitoring System

System Composition

This system consists of data servers, WEB servers, monitoring equipment, and is complemented by powerful data analysis software, maximizing information integration and resource sharing. With the implementation of this system, it can automatically collect historical and real-time data from various monitoring points. Through the WEB server, workstations within the system can access historical and real-time data from these points, enabling analysis of historical data and unified management and scheduling of all monitoring points.

Data server

This system utilizes SQL Server 2000 for database storage, automatically collecting real-time and historical data from various monitoring points and saving it for analysis. The database employs dual hard drives in mirror configuration, enhancing data loss prevention capabilities.

Web Server

Users can access the web server to view real-time data waveforms, spectrums, etc., for various sites, and can generate reports for any time period from historical data statistics.
