ETRZ-800A Sweep Frequency Response Analyzer

ETRZ-800A FRA is used to test transformer winding deformation power transformer ≥6 kV and other special purposes. Power transformer will inevitably suffer from the impact of various short-circuit currents or physical impacts during operation or transportation. Under the action of strong electrodynamic force generated by short-circuit currents, transformer windings may lose stability, resulting in permanent deformation such as local distortion, bulging or displacement, which will seriously affect the safe operation of the transformer.

Product characteristics

1. Characteristics of transformer windings are measured with frequency sweep method. Deformations of windings such as distortion, swell or displacement of 6kV and above transformer are measured by detecting amplitude-frequency response characteristics of each winding, not requiring lifting of transformer enclosure or disintegration.

2. Quick measuring, measuring of a single winding is within 2 minutes.

3. High frequency accuracy, higher than 0.001%.

4. Digital frequency synthesis, with higher frequency stability.

5. 5000V voltage isolation fully protects safety of the testing computer.

6. Able to load 9 curves at the same time and automatically calculate parameters of each curve and diagnose winding deformations to provide the reference diagnosis conclusion.

7. Analysis software has powerful functions .

8. Software management is humanized with high degree of intelligence. You only need to click a key to complete all measurements after setting of parameters.

9. The software interface is concise and vivid, with clear menus of analysis, save, report export, print, etc.
