Upgraded Manufacturer Kdzd5000z High Resolution Mass Power Quality Analyzer Data Logger for Grid Detection Use

 
The KDZD5000Z power quality analyzer is a comprehensive testing instrument developed by our company specifically for on-site testing, which is three-phase, multifunctional, intelligent, and has simple human-machine operation. It has the characteristics of easy use, large LCD color screen display, high resolution, bilingual operation interface in Chinese and English, and box type structure shell. It can simultaneously measure 4 currents (ABC three-phase and neutral line currents), 4 voltages (ABC three-phase voltage and neutral line to ground voltage), peak values of current and voltage, maximum and minimum values over a period of time, three-phase imbalance, short-term voltage flicker, transformer K-factor, active power, reactive power, apparent power, power factor, displacement power factor, active energy, reactive energy, apparent energy, harmonic ratio, total harmonic distortion, etc; Real time waveform, phasor diagram, and harmonic ratio bar chart displaying current and voltage; Dynamically capture instantaneous changes in voltage and current, monitor startup current, monitor various power parameters and generate alarm lists, record test data for a long time and generate trend curve graphs, and other functions.

The KDZD5000Z power quality analyzer adopts a dual processor architecture of DSP and ARM. DSP is responsible for data acquisition and algorithm processing, while ARM is responsible for communication protocol and human-machine interface processing; Two 16 bit resolution 4-channel synchronous sampling chips from ADI are used for analog signal acquisition, achieving a maximum sampling rate of 1MSPS, ensuring channel accuracy and information integrity, and not missing any transient changes in the power grid, making the detection of transient waveforms, sudden rises and falls, instantaneous interruptions, etc. more accurate; The working frequency of DSP is above 200MHz, which can monitor the power grid in a timely manner and dynamically adjust the sampling frequency to achieve synchronization between power frequency and sampling frequency; Using a 5.6-inch LCD color screen display with a resolution of 640dots × 480dots, different colors are used to distinguish and display the parameters, waveform diagrams, phasor diagrams, and harmonic ratios of each phase, allowing users to more efficiently and intuitively understand the status of power grid parameters. 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 100 seconds of startup current waveforms. Built in 2G memory card is used to store long-term trend curve records, while also recording 20 power parameters (can be selected according to needs). It can be collected and recorded once every 5 seconds, and can record and store trend curve records for up to 300 days.
 
The power quality analyzer, also known as intelligent three-phase power quality analyzer, multifunctional power quality analyzer, three-phase power quality analyzer, etc., is suitable for power, petrochemical, metallurgical, railway, industrial and mining enterprises, scientific research institutions, metrology departments, etc. Suitable for analyzing and diagnosing electrical parameters such as voltage, current, power, electrical energy, harmonics, phase, etc.
