Estimated delivery : 30 Days; MOQ : 1 PCS
Product Introduction Overview
Frequency Response Method (Chinese and English versions available)
Embedded computer supports Windows 32-bit/64-bit
The instrument comes with a high-performance embedded industrial computer, so you can complete the measurement without carrying a laptop.
The transformer winding deformation tester quantifies the response changes of the transformer's internal winding parameters in different frequency domains, and determines the degree of change of the transformer's internal winding according to the size of the change value, the amplitude of the frequency response change, the area and the trend of the frequency response change. It can then judge whether the transformer has been severely damaged and whether it needs major repairs based on the measurement results.

Features :
The acquisition control adopts a high-speed, highly integrated microprocessor.
USB interface for communication between laptop and instrument.
By integrating industrial computers with measuring instruments, there is no need to use mobile computers at the measurement site.
The hardware movement adopts DDS dedicated digital high-speed scanning technology (USA). Through testing, it can accurately diagnose faults such as winding distortion, bulging, displacement, tilt, turn-to-turn short circuit deformation and phase-to-phase contact short circuit.
High-speed dual-channel 16-bit A/D sampling (on-site test, the waveform curve changes significantly when the tap switch is changed).
The signal output amplitude is software-adjustable, with a maximum peak amplitude of ±10V.
The computer generates an electronic document (Word) with the test results.
The instrument has dual measurement system functions of linear frequency sweep measurement and segmented frequency sweep measurement, and is compatible with the measurement modes of the two current domestic technical schools.
The amplitude-frequency characteristic meets the national technical indicators for amplitude-frequency characteristic testers. The horizontal axis (frequency) has two types of linear and logarithmic divisions, so the printed curve can be a linear or logarithmic division curve, and users can choose according to actual needs.
Automatic analysis system for test data
Compare the winding similarity between phases A, B and C horizontally
The analysis results are:
Very good consistency
Good consistency
Poor consistency
The consistency is very poor,
Compare AA, BB, CC longitudinally to retrieve the original data and current data in phase to compare winding deformation
The analysis results are:
Normal winding
Slight deformation
Moderate deformation
Severe deformation
Word electronic documents can be automatically generated for saving and printing.
The instrument fully meets the technical requirements of the power standard DL/T911-2004 "Frequency Response Analysis Method for Power Transformer Winding Deformation".
