| Transformer Winding Deformation Detector Darui Electric recommends Product Features: 1.USB communication interface between PC and instrument. 2.Automatically generate Word electronic documents for saving and printing. 3.Computer generates electronic document (WORD) from test results. 4.Signal output amplitude can be adjusted by software, peak ±10V. 5.Acquisition control adopts high-speed, highly integrated microprocessor. 6.Finished circuit board with special surface treatment, resistant to water and harmful gas pollution. 7.Laptop and measuring instrument powered by isolated power supply to eliminate external interference. 8.High-resolution dB measurement, dual-channel 16-bit A/D (on-site test changing tap changer gives obvious output change). 9.High-stability components selected; repeated test on same phase yields measurement repeatability above 99.5%. 10.Instrument has dual measurement system functions: linear sweep measurement and segmented sweep measurement, compatible with current domestic two technical schools of measurement modes. 11.Amplitude-frequency characteristics meet national technical indicators for amplitude-frequency characteristic testers. The horizontal axis (frequency) has both linear and logarithmic scales, so the printed curve can be either linear or logarithmic, user can choose according to actual needs. 12.Fully meets the technical conditions of the electric power standard DL/T911-2004 "Frequency Response Analysis Method for Power Transformer Winding Deformation". 13.Hardware movement adopts DDS dedicated digital high-speed sweep technology (USA). Through testing, it can accurately diagnose faults such as winding distortion, bulging, displacement, tilting, inter-turn short circuit deformation, and phase-to-phase contact short circuit. 14.Automatic analysis system for test data; horizontal comparison of winding similarity among phases A, B, C yields results: ①Very good consistency ②Good consistency ③Poor consistency ④Very poor consistency; vertical comparison of A-A, B-B, C-C by retrieving original data and current data for same phase for winding deformation comparison yields results: ①Normal winding ②Mild deformation ③Moderate deformation ④Severe deformation.
