Product description
Product parameters
Reference standard: DL/T911-2004.
Features:
● Single-phase transformer double (three) winding, three-phase double winding, three-phase three-winding test;
● When testing single-phase transformers, three curves can be loaded at the same time, three-phase comparison is carried out, the relevant parameters of each curve are automatically calculated, the correlation is displayed, the deformation of the winding is automatically diagnosed, and the diagnosis conclusion is given;
● The calculation function of the mathematical correlation coefficient of the graph curve can analyze the deformation type, deformation area estimation and deformation degree, such as the overall displacement, the overall compression (or stretching) of the coil, and the local compression (or pull) by using the relationship between the typical deformation and the spectral change. Extension), short circuit between turns, etc.;
● Detection data automatic analysis system, horizontal comparison of winding, similarity between A, B, C three-phase, the results are: 1 consistency is good 2 consistency is good 3 consistency is poor 4 consistency is poor, vertical Compare AA, BB, CC to obtain the winding deformation comparison between the original data and the current data in the same phase. The result is: 1 normal winding 2 mild deformation 3 moderate deformation 4 severe deformation 4 .
