4.4 Data Echo
The system is able to echo saved data. By selecting name of power station, name of
transformer, test category and time, as well as winding type and time in turn in area F, the
completed test result is called out. By default, the data is displayed at the position of the
first curve and displayed downwards with progressive increase of the selection result.
When the number of curves comes to the maximum (9 curves), the curve no longer
increases and you may select the curve to be replaced for progressive replacement in this
case. When a curve is decided not requiring analysis, you may right click “clear curve” on
the curve description information (E) so that the curve will be removed out of the analysis
list automatically.
Curves in area E are automatically divided into three groups, 1-3 as a group, 4-6 as a
group and 7-9 as a group and correlation analysis of each group of curves is performed
inside the respective group. Therefore, it is required to ensure the curves to be analyzed
are within the same group, or otherwise you cannot get correct analysis result.
When “analysis”
is clicked after selection of curve, the report display window will
pop up at the left side. All other operations are the same as operations described in 4.3.
4.5 Report Saving Position
Report is saved under folder of disk D with the folder hierarchy of:
D: \FRA_data\test print time. doc or test print time. jpg.
The report could be WORD document or JPG photo, subject to the option selected in
saving.
V.Tester Maintenance
The section provides basic maintenance data. Please do not try to disintegrate, modify
and repair the Sweep Frequency Response Analyzer.
5.1 Basic Maintenance
Regularly scrub surfaces of the tester and its accessories with a clean cloth.
Put the tester at a clean place with low humidity and protect it against entry of dirt and dust.
Put the tester into its packing case when not used and keep the packing case level.
5.2 Senior Maintenance
To be proceeded by professional technicians of the Company.
VI.Precautions
Please read carefully the Instructions for the Sweep Frequency Response Analyzer!
Operators must read carefully the Instructions before use.
The tester is applicable to testing of transformer winding deformation with frequency
response method.
