portable transformer winding resistance testing machine sweep frequency response analyzer

Sweep Frequency Response Analyzers introduction:

Transformer winding deformation tester for testing 6kV and above power transformers and other special purpose transformers, power transformers running or during transport will inevitably have to suffer the impact of a variety of short-circuit current fault or physical impact, in the short-circuit current Under the powerful role of electric power transformer windings may lose stability, leading to local distortion, drum kits and other permanent deformation or displacement phenomenon, which will seriously affect the safe operation of the transformer. According to the national power industry standard DL / T911-2004 winding deformation frequency response analysis using measurement transformer is a frequency response characteristics detected by the amplitude of each transformer winding, and the test results were vertical or horizontal comparison, according to the frequency response characteristic of change degree, determine the deformation of transformer windings may occur.

Sweep Frequency Response Analyzers characteristics:

• sweep method using the measured characteristics of the transformer winding, no transformer hanging hood, removable case, detected by amplitude frequency response characteristics of the windings of the transformer 6kV and more accurate measurement of distorted winding drum kits or shifted deformation.
• measurement speed, single winding for measuring time within three minutes.
• frequency accuracy is very high, higher than the 0.001 percent accuracy.
• digital frequency synthesis, higher frequency stability.
• 5000V voltage isolation, the full protection of computer security tests.
• can be simultaneously loaded 9 curves, each curve related parameters are automatically calculated, automatically diagnose winding deformation, given the reference diagnostic conclusions.
• powerful software analysis, software, hardware indicators meet the national standard DL / T911-2004.
• software management humane, high intelligence, after the parameters are set, just press a button to complete all measurements.
• software interface is simple and intuitive, analysis, storage, export report, print menu glance.
