Transformer Winding Deformation Analyzer
- Wrindu
- RDRB-Ⅳ
1. The RDRB-Ⅳ Transformer Winding Deformation Sweep Frequency Response Analyzer is used for power transformers with a voltage grade of 6kV and above and other transformers with special purposes.
2. Transformer Winding Deformation Analyzer are inevitably vulnerable to impulses from various fault short-circuit currents or physical collisions during operation and transportation. These impulses can exert powerful electro-dynamic forces on the transformer winding, potentially causing permanent deformations such as local distortion, swelling, or dislocation, which can severely affect the safe operation of the transformer.
3. Deformation of the transformer winding is measured using the frequency response analysis method, following the national standard DL/T911-2016/IEC60076-18 for the electric power industry. This method involves detecting the amplitude-frequency response characteristics of each transformer winding and making vertical or horizontal comparisons of the detection results to judge possible deformation based on changes in amplitude-frequency response characteristics.
Features
Characteristics of transformer winding 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.
Quick measuring, measuring of a single winding is within 2 minutes.
High frequency accuracy, higher than 0.001%.
Digital frequency synthesis, with higher frequency stability.
5000V voltage isolation fully protects safety of the testing computer.
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.
Analysis software has powerful functions and software and hardware indicators satisfy national standard DL/T911-2016/IEC60076-18.
Software management is humanized with high degree of intelligence. You only need to click one key to complete all measurements after setting of parameters.
The software interface is concise and vivid, with clear menus of analysis, save, report export, print, etc.
