The requirements are also getting higher and higher, so we provide this kind of measurement and analysis instrument that can troubleshoot complex power systems more quickly and accurately, and monitor and maintain power quality parameters more comprehensively and systematically.ES4000 power quality analyzer adopts DSP+ARM dual-processor architecture, DSP is responsible for data acquisition and algorithm processing, ARM is responsible for communication protocol and human-machine interface processing; analog signal acquisition uses 2 pieces of ADI company's 4-channel synchronization with a resolution of 16 bits Sampling, to achieve the highest sampling rate of 1MSPS, to ensure the accuracy and information integrity of the channel, to ensure that any transient changes in the power grid will not be missed, and to detect transient waveforms, swells and sags, and instantaneous interruptions. Accurate; DSP operating frequency is above 200MHz, which can monitor the power grid in time and dynamically adjust the sampling frequency to achieve synchronization of power frequency and sampling frequency; 5.6-inch LCD color screen display with a resolution of 640dots × 480dots, with different colors to display the parameters of each phase, Waveform diagrams, phasor diagrams, and harmonic ratio diagrams enable users to understand the state of power grid parameters more efficiently and intuitively. The built-in flash memory can simultaneously store 60 sets of screenshots, 150 sets of transient voltage/current capture waveforms, 12800 sets of alarm logs, and the startup current detection mode can continuously capture 100s of startup current waveforms. The built-in 2G memory card is used to store long-term trend curve records, and records 20 power parameters at the same time (can be selected according to needs).Power quality analyzer, also known as intelligent three-phase power quality analyzer, multi-functional power quality analyzer, three-phase power quality analyzer, etc., is suitable for electric power, petrochemical, metallurgy, railway, industrial and mining enterprises, scientific research institutions, measurement departments, etc. . It is especially suitable for comprehensive analysis and diagnosis of all voltage, current, power, electrical energy, harmonics, phase and other electrical parameters.Ⅱ. Basic Function Introduction1.

(Select 20 parameters at the same time and record once every 5 seconds, about 300 days can be recorded)5. Alarm function:Limits can be set for the selected parameters as required, monitoring whether they exceed the limits, and alarm logs are generated when the limits are exceeded, such as voltage overvoltage, current overcurrent, unbalance exceeding the limit, a certain harmonic ratio exceeding the limit, frequency Over limit, active power over limit, total harmonic distortion over limit, etc., up to 40 groups of alarm monitoring parameters can be set, and each group can be set with different monitoring parameters (including 50 harmonics, a total of 123 different parameters) and limit value to set the minimum time for exceeding the limit. Up to 12800 groups of alarm log records can be stored.6. Screenshot function:On any test page, you can take a screenshot to store the current screen, and automatically save the recording time and the test mode you are in. Such as saving current and voltage waves, harmonic histograms, phasor diagrams, etc. Up to 60 groups of screenshots can be saved at the same time7.
