Portable Transformer SFRA Tester Short Circuit Impedance Tester

Product Features:

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 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 in Word format;
8. Using 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 need;
12. Automatic detection of data analysis system, horizontal comparison A, B, C three-phase windings similarity comparison, the results as follows: perfect consistency,good consistency , ordinary consistency, 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: normal winding deformation, mild winding deformation, moderate winding deformation, severe deformation deformation;
13. Automatically generated Word electronic documents, for saving and printing;

14. It fully meet the electricity standard DL/T911-2004 " power transformer winding deformation Frequency Response Analysis" technical conditions .
