HZCR-5000 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.
HZCR-5000 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.
