HZCR5000 Digital Power Analyser Power Quality And Energy Analyzer

1.Power Quality And Energy Analyzer Introduction

HZCR5000 Power Quality Analyzer is a comprehensive test instrument carefully developed by our company and specially designed for field test of three phases, multi-functional and intelligent, concise man-machine operation. It is easy to use, large LCD screen display, high resolution, interface in both Chinese and English, shock-proof shell structure and so on. Can simultaneously measure the 4-channel current (ABC three phase and neutral wire current), 4-channel voltage (ABC three-phase voltage and neutral line voltage to ground), the peak value of current voltage,  maximum/minimum value over a period, three-phase imbalance factor, short-time voltage flicker, transformer K factor, active power, reactive power, apparent power, power factor and displacement power factor, active power, reactive power, apparent power, total harmonic distortion and harmonic, etc; Display real-time waveform, harmonic ratio bar charts of current voltage; Dynamically capture instantaneous change of voltage current, monitoring starting current, monitoring the power parameters and generate the alarm list, generate the trend chart for a long time record test data.

In the current power applications, more and more large power equipment, power grid fault have become more and more complex, with development of the industry, it put forward high request more and more to quality that electric energy. We provide this power quality analyzer for that, which you can troubleshoot of complex power system more quickly and accurate, and monitoring and maintenance of power quality parameters more comprehensive and systemic.

HZCR5000 Power quality analyser adopt DSP + ARM double processor architecture, DSP is use for data collection and the processing of algorithm, the ARM is use for the communication protocol and the man-machine interface processing; Analog signal acquisition is by 2 pieces AD7655 of ADI company. Resolution for AD7655 is 16 bit and it is 4 channel synchronous sampling. The highest sampling rate can reach 1 MSPS, to ensure the accuracy of the channel and the information integrity, and wouldn’t miss any transient changes in the grid, can more accurate to detect the transient waveform rising and dropping drastically, and waveform instantaneous interrupt; DSP working frequency is over 200 MHZ, to be able to timely monitoring of the power grid and dynamically adjust the sampling frequency to realize synchronization of power frequency and sampling frequency; Using a 5.6 -inch LCD color screen display, a resolution of 640 dots x 480 dots, with different display color difference between the parameters of phase, waveform, vector diagram, harmonic ratio, the user can be more efficient and more intuitive understand the state of power grid parameters. Built-in flash memory can store 60 group of screenshots at the same time, 150 groups of capture transient voltage/current waveform figure, and 12800 groups of alarm list. Starting current detection model can continuously capture starting current waveform for 100 s. Built-in 2G memory card to store the trend curve record, simultaneous recording 20 parameters (can choose according to need) collect data for once every five seconds, trend curve records can be stored for 300 days.

Power Quality Analyser also named: Intelligent Three Phase Power Quality Analyser, Multifunctional Power Quality Analyser, which simultaneous with the functions of harmonic analyser, phase volt-ampere meter, electric parameter tester. It apply to electricity industry, petrochemical, metallurgy, railway, mining enterprises, scientific research institution, metrological department. Especially suitable for comprehensive analysis and diagnosis on all the voltage, current, power, power, harmonic, phase electric parameters.
