EM5230 Power Quality Analyzer is a high-precision comprehensive testing instrument meticulously developed by our company, specifically designed for on-site testing of three-phase power quality. The instrument features intelligence, complete functions, simple human-machine operation, and a bilingual (Chinese and English) operation interface. The instrument adopts a 7-inch touch color screen, is small in size, light in weight and easy to carry. It can be equipped with multiple types of current clamps. The instrument can simultaneously measure 4 channels of current (ABC three-phase and neutral line current), 3 channels of voltage, three-phase unbalance degree, active power, reactive power, apparent power, harmonic ratio, total harmonic distortion degree, etc. Display real-time waveforms and phasor diagrams of current and voltage; Dynamic capture of instantaneous changes in voltage and current, monitoring of starting current, monitoring of various power parameters and generating alarm lists, long-term recording of test data and generation of trend curve graphs, and other functions.
In current power applications, faults caused by an increasing number of large-scale electrical equipment and increasingly complex power grid systems are becoming more and more complex and difficult to troubleshoot. Moreover, due to the development of various industries, the requirements for power quality in power grids are also getting higher and higher. Therefore, we provide this method that can more quickly and accurately eliminate faults in complex power systems. Measurement and analysis instruments for more comprehensive and systematic monitoring and maintenance of power quality parameters. The EM5230 Power Quality Analyzer features a 7-inch touch color screen display, which uses different colors to distinguish and show the parameters, waveform diagrams, vector diagrams, and harmonic ratio diagrams of each phase, enabling users to understand the status of power grid parameters more efficiently and intuitively. The stored data is uploaded to the computer through the USB communication interface and the upper computer software for further data analysis. The power quality analyzer, also known as the intelligent three-phase power quality analyzer, multi-functional power quality analyzer, three-phase power quality analyzer, etc., also has the functions of harmonic analyzers, phase volt-ampere meters, power parameter testers and other instruments. It is applicable to power, petrochemical, metallurgy, railway, industrial and mining enterprises, scientific research institutions and universities, metrology departments, etc. It is especially suitable for comprehensive analysis and diagnosis of all electrical parameters such as voltage, current, power, energy, harmonics and phase.
