Power Transformer Winding Deformation Test Equipment Transformer Winding Analyzer
This Transformer Winding Deformation Tester Is For Testing Of Power Transformer (Voltage Level At Or Above 6kV) And Other Transformers With Special Purpose. The Power Transformer Is Inevitably Vulnerable To Impulse Of Various Fault Short-Circuit Current Or Physical Collision In The Process Of Operation And Transportation. The Transformer Windings May Lose Stability Under The Powerful Electro-Dynamic Force Exerted By Such Short-Circuit Current, Which Could Result In Permanent Deformations Such As Local Distortion, Swell Or Dislocation And Will Severely Affect Safe Operation Of The Transformer. Deformation Of Transformer Windings Can Be Measured With Frequency Response Analysis Method According To National Standard DL/T911-2004 For Electric Power Industry, I.E. Detect Amplitude-Frequency Response Characteristics Of Each Transformer Winding And Make Vertical Or Horizontal Comparison Of The Detection Result To Judge Possible Deformation Of The Transformer Winding Ba.
Features
1. In the test process only need to remove the transformer connection bus.
3. Sweeping frequency up to 10MHz, scanning interval can be 0.25kHz, 0.5kHz, 1kHz for multiple analysis
4. High intelligent, auto range adjustment, auto sampling frequency adjustment.
5. Windows platform, compatible with Win98 / 2000 / XP / Win7 / Win8 / Win10 system.
6. Historical curve comparison analysis, max 6 curves observation, auto analysis and diagnosis system
7. Auto save environment parameters and testing results, color printing function.
8. Humanized software design, more convenient to use.
9. Auto complete the test after wiring, during the measurement
check the historical curves or stop at any time.
10. Measurement time less than 60 seconds for every phase, 10
minutes for whole transformer windings.

Test procedure and cautions
1. First check if the transformer is properly grounded, and the
casing leads are all disconnected.
2. Record if the nameplate data and original conditions of the
tested transformer are normal, and the position of tap-changers
under the current test conditions and carefully enter it into the
registration window.
3. Create the a subdirectory for test data file of the transformer
tested; after the test, copy the measurement data to the directory,
and sort the data well.
4. Data saving format: file is saved in ASCII format, and the user
can read and modify it with a variety of text -editing software to.
5. Test the transformer that just stops running. Before the
measurement, allow it to cool down the heat; but in the entire
measurement process, stop cooling to maintain the temperature, so
as to prevent temperature changes in the measuring process
affecting the consistency of measurement results.
