Three Phase Winding Sweep Frequency Response Analyzer for Simultaneous Measurement

XHBX1501S Transformer winding deformation tester
SFRA Test kit transformer

Product description

Transformer winding deformation tester based can make accurate diagnosis on the transformer internal fault based on the measurement of the characteristic parameters of transformer windings inside, using the frequency response analysis (FRA) method developed and improved by the developed countries.
It applies to the detection of internal structure fault in 63kV-500kV power transformers.

Main features

1. The test can be carried out without lifting the cover and disassembling the transformer.

2. Adopt the most popular sweep method to measure.

3. This instrument can measure transformers those are above 6kV.

4. It uses a split structure, test host and the host computer were connected by USB or network connection, it can use freely when it was plugged.

5. The field wiring is simple, easy to use.

6. Measuring dynamic range: -100dB ~ 20dB.

7. The analysis software is powerful, and the software and hardware indicators meet the national standard DL/T911-2004.

8. Sweep measurement using linear or logarithmic distribution.

9. The response channel has multiple ranges and automatically adjusts the range during the measurement process.
