The Dewesoft power analyzer redefines analysis and testing process of the power transformer with its unique set of software tools and flexible hardware.
The testing of power transformers makes a couple of different measurements necessary, which are described in the international IEC 60076 standard.
Our data acquisition systems provide key features for complete power transformer testing:
The Power quality module allows measuring harmonics of the voltage and the current up to some hundred kHz. The data can be represented in the percentage of the fundamental frequency as required for the no-load current according to IEC 60076 standard.
The power quality module also automatically calculates the zero-sequence impedance which is required in the power transformer testing.
The math library allows us to automatically calculate parameters like the magnetizing current, the iron losses, the main inductance for example out of the no-load test or the stray inductances out of the short-circuit tests.
For more information check the power quality application page.
Power and efficiency analysis of the transformers require the highest accuracy of the power calculation for all phase angles. Especially analysis at lower power factors is very difficult with conventional measurement equipment.
The additional sensor calibration functionality allows correcting the behavior of voltage and current transducers for amplitude and phase over the whole frequency range.
Furthermore, IEC 60076-1 standard requires the correction of measured power losses depending on the temperature. Dewesoft power analyzer makes it easy to measure all the required temperatures (winding, oil, ambient, etc.) perfectly synchronized to voltage, current and other measured parameters.
In addition, it’s possible to automatically calculate the corrected power losses. You can also measure the power of oil pumps and fan motors, and even the sound level of the transformer according to IEC 60551 standard.
This covers all the possible tests that you can experience with power transformers, and Dewesoft can cover them all with one single device.
For the most typical configuration, we suggest R2DB DAQ system with optional additional KRYPTON DAQ for temperature inputs:
Compact, mobile, and portable data acquisition systems that feature a built-in data logger, powerful data processing computer, multi-touch display, and internal batteries for maximum portability.
High-accuracy current sensors for AC/DC current measurement and power analysis. From current clamps to high-precision zero flux current transducers and Rogowsky coils.
Our current transducers are a perfect fit for our data acquisition systems and can precisely measure AC/DC current with up to 0.03% accuracy. TEDS equipped for automatic detection and setup.
DewesoftX is an award-winning data acquisition software for test & measurement and monitoring. Experience data recording, signal processing, and data visualization like never before.
DewesoftX DAQ software received multiple international awards, is innovative and easy-to-use, but at the same time very deep in functionality. Our mission is clear - one software for all test and measurement applications.
The Dewesoft power quality analyzer can measure all the power quality parameters according to IEC 61000-4-30 Class A. In comparison to other power quality meters, ours are able to do more detailed power quality analysis. Raw data storing, behavior at faults, calculation of additional parameters, etc.
