Characteristics of the products
1, Collection control adopt high-speed , highly integrated microprocessor.
2 , Notebook with USB interface for communication between the instrument
laptops and USB interface for communication between instruments .
3, there is communication wireless blue-tooth interface between laptop computer and instruments .
4 , the hardware chipset adopt DDS dedicated digital high-speed sweeping technology ( USA ) , though the testing, can accurately diagnosed the winding distorted, drum kits, shift, tilt, deformation of inter-turn short circuit and phase to phase short circuit fault.
5 ,high resolution dB value measurement, dual-channel 16-bit A / D ( on-site test change the tap , means obvious output change ) .
6 , the signal output amplitude can be adjusted by software, the maximum amplitude peak ± 10V.
7 , the computer generates an electronic document testing results (Word)
8, choose precision, high stability components, to the same-phase repeated testing, the measurement repetition rate to 99.5%.
9, the finished circuit board ,with a special process on the surface, with water-proof and anti-harmful gas functions .
10 , the instrument has a linear frequency sweep measurements and segmented sweep measurement dual measurement system features two techniques compatible with the current domestic genre measurement mode
11 , the amplitude-frequency characteristics meet the national tester technical indicators standard. Abscissa ( frequency ) with linear and logarithmic indexing, so the printed curve can be linear pitch curve points, also can be a logarithmic curve, the user can choose according to actual needs .
12, automatic detection of data analysis system, horizontal comparison A, B, C three-phase windings similarity comparison, the results as follows: ①perfect consistency,②good consistency , ③ordinary  consistency, ④ poor consistency. Vertical comparison, A-A, B-B, C-C obtain the original data and the current data phase to phase winding deformation comparison between, the results as follows: ①normal winding deformation, ②mild winding deformation, ③moderate winding deformation, ④severe deformation deformation .
13 , automatically generated Word electronic documents, for saving and printing .
14 , the instrument fully meet the electricity standard DL/T911-2004 " power transformer winding deformation Frequency Response Analysis" technical conditions
