3 Phase Standard Reference Energy Meter Class 0.02
ZXDN-301 Three-Phase Standard Electricity Meter
Product Introduction :
ZXDN-301 Three-Phase Standard Electricity Meter is a high-precision multi-function and wide range standard electricity meter developed by our company. Its accuracy grade is 0.02. Light weight, small size, high precision, DSP, embedded technology, automatic temperature balance technology and other compensation technology, stable index, rich functions, novel interface, clear and simple operation, reliable work. It can be widely used in electric energy metering industry, electric energy laboratory and other relevant departments. It can not only be used in the laboratory, but also carry to the field work.
Standard portable aluminum case, smaller volume (currently the
volume of domestic similar products 355×145×185mm) lighter weight
(7.5kg), more convenient to carry.
Wide range measurement: voltage measurement range (phase voltage) :
1 ~ 560V
Current measurement range: 10mA ~ 120A
Multiple methods of measurement: it can measure ac voltage,
current, power (active power, reactive power, apparent power) and
electric energy in 4 quadrant under various wiring modes such as
single-phase, three-phase four-wire Y/ three-wire Δ; The reactive
power and electric energy can be measured in many ways, such as
true reactive power, quadrate reactive power and artificial neutral
reactive power.
Multi-functional measurement:
A. Voltage, current, phase, frequency, active power, reactive
power, power factor, error and other basic measurement functions.
B. Voltage, current and power stability measurement (up to 5 power
stability algorithms).
C. Measurement of voltage and current three-phase amplitude
asymmetry.
D. Measurement of voltage and current three-phase unbalance.
E. Measurement of phase misalignment.
F. Vector graph display, a variety of vector graph display methods
(clockwise rotation, counterclockwise rotation; 12:00 o 'clock,
3:00 o 'clock base position optional; Reference datum variable;
Phase display mode: 0 ~ 360° or ±180° can be set) to meet various
display habits.
G. Waveform display, harmonic analysis, distortion calculation.
Spectrum graph display; Can display harmonic amplitude, content,
phase. The spectrum diagram has the function of magnification.
H. Demand measurement
I. Measurement of magnetic induction intensity in space.
J. Measurement of pressure drop at the same end of the device.
K. Measure the meter constant and frequency.
L. Fundamental wave power measurement.
M. The error (active power, reactive power, apparent, voltage and
current) of three different types of meters can be verified at the
same time.
N.3 pulse outputs, constant can be set separately (automatic or
manual setting), constant types can also be set separately: active
power, reactive power, apparent, voltage, current.
O. It can verify the comprehensive error of the device composed of
three single-phase meters.
P. Can be used as three single-phase standard meters.
Fundamental wave power measurement: it can measure full power
(including fundamental wave and harmonic wave power), and can only
measure fundamental wave power.
Electric energy error verification: it can verify the estimated
value of electric energy measurement error and standard deviation
of electric energy meter and electric energy meter verification
device. And the pulse number, the calibration constant can be set
automatically to improve the work efficiency. Especially the
calibration device for multi-constant standard meter and
electricity meter is more convenient to use. Special compensation
technology, in small load, because the load is too small (energy
pulse frequency is too low) will not cause the error jump too big.
Display current error, standard deviation estimate, average error.
Harmonic analysis: analysis of power frequency voltage, current 51
times below harmonics.
Data and graphic display: can intuitively display the measurement
status and a variety of measurement data. Can intuitively display
the measured voltage, current waveform, voltage, current phase
vector diagram, harmonic analysis wave bar diagram.
Manual or automatic range switching.
With storage function, can store 30 groups of data records. And can
be retrieved according to the conditions.
with pinyin input method: can input Chinese characters, letters,
symbols
Wiring: wide range current input terminal common, change the
current without changing wiring, easy to use.
multi-purpose: can be used as a standard meter, also can be used as
electricity meter verification device tester. Can be used alone,
can also be used with PC communication remote control, can also be
used with verification device.
Multiple communication interfaces: RS485, RS232, USB, using
asynchronous communication: baud rate can be set.
6.4 inch 640×480 dot matrix TFT color LCD display, clear display,
vivid color.
Operation: humanized design, reasonable combination of functions, very simple operation.
