Audited Supplier KGRB-II Transformer Winding Deformation Tester (embedded in computer) Short Circuit Impedance Tester
Product Introduction
KGRB-II transformer winding deformation tester (embedded computer) by detecting the amplitude-frequency response characteristics of each winding of the transformer, and comparing the detection results vertically or horizontally, according to the degree of change in amplitude-frequency response characteristics, judge the winding deformation that may occur in the transformer.
KGRB-II transformer winding deformation tester (embedded computer) has the function of linear sweep frequency measurement and segmented sweep frequency measurement dual measurement system, compatible with the current two domestic technical schools of measurement mode.
KGRB-II transformer winding deformation tester (embedded in computer) is convenient to carry, high-speed dual-channel 16-bit A/D sampling (field test changes the tap-changer, the waveform curve has a clear change).

KGRB-II Transformer Winding Deformation Tester (embedded in computer) Short Circuit Impedance Tester
Product Characteristics
1, acquisition control using high-speed, highly integrated microprocessor.
2. USB interface for communication between laptop and instrument.
3, the hardware movement adopts DDS special digital high-speed sweep frequency technology (USA), through the test can accurately diagnose winding distortion, bulge, shift, tilt, turn short circuit deformation and interphase contact short circuit and other faults.
4, high-speed dual-channel 16-bit A/D sampling (field test changes the tap-changer, the waveform curve has a clear change).
5, signal output amplitude software adjustment, the maximum peak ±10V.
6, the computer will automatically analyze the test results and generate electronic documents (Word).
7, the instrument has linear sweep frequency measurement and segmented sweep frequency measurement dual measurement system function, compatible with the current domestic two technical schools of measurement mode.
8, amplitude-frequency characteristics in line with the national amplitude-frequency characteristics tester technical indicators. The horizontal coordinate (frequency) has two kinds of linear indexing and logarithmic indexing, so the printed curve can be a linear indexing curve or a logarithmic indexing curve, and users can choose according to actual needs.
9, detection data automatic analysis system
(1)The winding similarity is compared between the three phases A, B and C
(2)The analysis results are as follows:
(3)The consistency is good
(4)Good consistency
Poor consistency
Poor consistency,
Longitudinal comparison A-A, B-B, C-C The winding deformation is compared between the original data and the current data in phase
The analysis results are as follows:
(1)Normal winding
(2)Mild deformation
(3)moderate deformation
(4)Severe deformation
10, can automatically generate Word electronic documents for saving and printing.
11, the instrument fully meets the technical conditions of the power standard DL/T911-2004 "Frequency response Analysis of power transformer winding deformation".
