NRBX Sweep Frequency Response Analyzer is based on the measurement of the windings characteristic parameters inside the transformer, the tester using the world's developed countries sound internal fault frequency response analysis (FRA) method, able to make an accurate internal transformer fault judgment.
Overview
Product character
• Use high-speed high integration microprocessor to sample and control.
• Use USB to connect the notebook PC and device.
• Communication wireless Bluetooth interface between the laptop and instruments.
• Hardware cassette mechanism adopts DDS (from America) can correctly detect the breakdown :distortion swell shift tilt inter-turn short circuit deformation and contacting short circuit inter-phase.
• High-speed dual channel 16 bit A/D sampling (the wave from curve will change obviously if change the tapping switch during the field tests.).
• The software can adjust the output signal range the maximum amplitude peak±10V.
• The computer automatically generating the test results to be Word document.
• Use precision high stability components the same phase repeat test measurement repetition rate > 99.5%.
• Finished circuit boards surface specially treatment with anti-water pollution and harmful gases.
• The device with two measurement system: linear scan and sectional scan.
• Amplitude-frequency characteristic comply the national technical specifications.
• Test data automatic analysis system horizontal compare the similarity of AB C the results as below:
(1) conformance is very good
(2) conformance is good
(3) conformance is bad
(4) conformance is very bad
Vertical compare A-A B-B C-C obtain the original data to compare the winding deformation with the test data in the same phase the results as below:
(1) normal
(2) slight deformation
(3) moderate deformation
(4) serious deformation
• Automatically generating Word document，convenient for customers to save and print.
