WP4000 frequency is a suitable for transformer, rectifier, inverter and other types of converters and motors, electrical products testing, energy efficiency evaluation and harmonic analysis of the wideband and high precision power analyzer, it is is an important instrument of power electronic technology, frequency conversion technology and new energy technology of high-speed development of the product and the sustained and healthy development.
WP4000 frequency conversion power analyzer led by the National Institute of variable frequency power meter (ATITAN frequency conversion power standard source) to provide measurement reference;
WWP4000 frequency conversion power analyzer can be traced all the accuracy indicators.
With the wide application of electromagnetic energy, the development of industrial technology changes with each passing day.
Electromagnetic energy in the creation of great wealth for mankind, but also bring some harm.
The electromagnetic environment is becoming more and more complex, and the good electromagnetic compatibility is the premise of instrument precision.
WP4000 variable frequency power analyzer using front-end digital technology, a fiber optic frequency transmitter and digital input of the digital host and transmit digital signals output by the digital quantity, front-end digital and optical fiber transmission can avoid the interference and attenuation in complex electromagnetic environment of transmission link itself, at the same time truncated sensor the most important interference ways, enhance the electromagnetic sensor and system compatibility.
WP4000 frequency conversion power analyzer uses unique large instrument technology,
the frequency conversion power transmitter and digital host through optical fiber
transmission to achieve the perfect integration of organic.
Variable frequency transmitter can achieve 100 V~15kV voltage,
100 A~7kA current, power and other parameters by direct measurement.
The power measurement system is composed of power analyzer,
voltage sensor, current sensor, auxiliary power supply and transmission line.
The accuracy of each component and the matching degree of each component will affect the precision of the system.
System accuracy is the target accuracy
Precision of components like a wooden barrel effect in length, the lowest precision components to the decisive role on the system accuracy,
the highest precision parts in the system of no avail.
WP4000 frequency conversion power analyzer uses front-end digital technology, the transmission of optical fiber and digital host, will not introduce errors,
the accuracy of the frequency converter is the precision of the system.
The global precision of the frequency conversion power analyzer
with the nominal global precision means that the frequency
conversion power analyzer can achieve the nominal accuracy
index within the range of the instrument.
Part of the imported high precision power analyzer with the best
precision point accuracy as the nominal accuracy,
while the nominal range of a wide range of nominal accuracy and
application of the scope of the disjointed.
and application of the scope of the disjointed.
Comparison of actual accuracy on using A type inverter power
transmitter WP4000 variable power analyzer and an imported high
precision power analyzer.
Comparison of imported high-precision power analyzer
nominal accuracy of 0.06%,
the nominal frequency range of 0.1Hz ~ 1MHz, it is clear that the
applicationof PWM wave measurement.
In fact, below 30Hz, the sine wave measurement accuracy is 0.55%,
and the PWM wave measurement accuracy of 1.8% WP4000
frequency conversion power analyzer in the 0.1Hz ~ 1500Hz
(currently traceable) within the sine wave and non sine wave
test accuracy are 0.1% of the nominal accuracy.
0.1% is the global accuracy.
Almost all of the instrument's precision index is to reflect the error of the reference,
the accuracy index is only valid in the full range, that is, the accuracy and range is an integral whole.
To determine whether the results are accurate, the relative error is concerned.
For example: the instrument range is 15kV, the accuracy is 0.1%, we can not judge whether the results are accurate:
If the measurement is 15kV, the measurement accuracy is 0.1%; if the measurement is 1500V, the measurement accuracy is 1%;
If the measurement is 150V, the measurement accuracy is 10%; if the measurement is 75V, the measurement accuracy is 20%.
WP4000 variable frequency power transmitter built-in 8 automatic seamless conversion range,
The accuracy of measuring 75V to 15kV in the 15kV range power unit is 0.1%!
Large signal and small signal can be measured accurately!
Once you have the WP4000 frequency conversi on power analyzer,
you can enjoy the price of VIP YINHE ELECTRIC’s several kinds
of electrical parameters testing virtual instrument software,
to achieve a variety of value-added features.
As long as you pay 1/10 of the price of other instruments,
you can have all kinds of electrical parameters testing and
testing instruments of the YINHE ELECTRIC.
Each variable frequency power transmitter is also known as the power unit, each power unit can measure the voltage and current of all the way, each WP4000 can be configured 1 ~ 6 power units. Multiple WP4000 can be synchronized through the synchronization of optical fiber, the data is transmitted through Ethernet to achieve the synchronous measurement of electrical parameters of any channel.
Power unit includes SP series frequency conversion power sensor and DT series digital transmitter. According to the different range (100 V ~ 15kV/100 A~7kA) and precision (0.05S3/0.1S3/0.2S3), there are a variety of types of power units to choose from.
