Transformer winding deformation test instrument for test 6kV and the above voltage grade power transformer and the other special uses of transformer, power transformer in run or transport process in the inevitable to to suffered various fault short-circuit current of impact or physical impact, in short-circuit current produced of powerful electric power role Xia, transformer winding may lost stability, led to local twisted, bulge or shift, permanent deformation phenomenon, this will serious effect transformer of security run. According to the State power industry DL/T911-2004 measurement of transformer winding deformation by frequency response analysis, through the detection of amplitude-frequency response characteristics of transformer windings, and the test results are vertical or horizontal comparison, according to the variability in the amplitude-frequency response characteristics, judge transformer winding deformation that may occur.

1, the main technical characteristics

Sweep method was used to measure the characteristics of transformer winding, no transformer hanging hood, disassembly of case, by detecting the amplitude-frequency response characteristics of windings, 6kV and above transformers, accurate measurement of the winding wires distortions, bulging or deformation of shift.

Fast measurement, winding of a single measurement time of 3 minutes or less.

Very high frequency accuracy, accuracy is higher than 0.001%.

Digital Frequency synthesis, high frequency stability.

5000V voltage isolation, adequate protection testing and computer security.

Can be loaded simultaneously 9 curve, the curve parameters calculated automatically, automatic diagnosis of winding deformation, gives diagnostic conclusions.

Powerful analysis software, the software, the hardware indicators meet the State power industry DL/T911-2004.

Software management, high intelligence, set parameters, just by pressing a key to complete all survey work.

Simple and intuitive software interface, analysis, storage, export reports, print menu at a glance.
