HM5010 Sweep Frequency Response Analyzer Operation Video
Product Overview
The HM5010 Sweep Frequency Response Analyzer is used for power transformer with voltage grade of 66kV and above and other transformers with special purpose. The power transformer is inevitably vulnerable to impulse of various fault short-circuit current or physical collision in the process of operation and transportation and the transformer windings may lose stability under the powerful electro-dynamic force exerted by such short-circuit current, which could result in permanent deformations such as local distortion, swell or dislocation and will severely affect safe operation of the transformer. Deformation of transformer windings is measured with frequency response analysis method according to national standard DL/T911-2016/IEC60076-18 for electric power industry, i.e. detect amplitude-frequency response characteristic of each transformer winding and make vertical or horizontal comparison of the detection result to judge possible deformation of the transformer winding based on change of amplitude-frequency response characteristics.
Products Features
- Use Windows platform compatible with Windows 2000/Windows XP/Windows7/windows8/ Windows10/Windows11.
- Use database to save test data and render concise and easy data management.
- 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.
- Software management function is powerful that takes into full account of site use demand. Measuring data is automatically saved and exported to form Word version test report (require installation of relevant Office software) or JPG photo report to facilitate the user to export test report.
- The software has distinctive humanized feature. Measuring conditions are mostly options, which exempt the need of many inputs and bring about easier operation.
- The software has high degree of intelligence. You only need to click one key to complete all measurements after connection of input and output signals.
- The software interface is concise, vivid and practical.
