Primary Function:
- The PFRS-25 is a Sweep Frequency Response Analyzer (SFRA). It’s designed to assess the internal mechanical condition of power transformers by measuring their frequency response.
- Essentially, it “fingerprints” the transformer’s electrical response across a range of frequencies. Changes in this “fingerprint” over time can indicate mechanical problems.
Key Features:
- SFRA Technology: Utilizes frequency response analysis to detect mechanical changes.
- Compliance: Compliant with industry standards such as IEC 60076-18 and IEEE C57.149.
- Portability: Designed for field use, allowing for on-site testing.
- Fast Sweep Time: It is designed to have very quick test times.
- Software Analysis: Comes with software for data analysis and comparison of test results.
- FRSL (Frequency Response Stray Loss): Has the ability to detect intra-strand short-circuits and overheating.
Applications:
- Detecting winding deformations, displacements, and looseness.
- Identifying core movements and damage.
- Locating shorted turns or open windings.
- Verifying the integrity of winding connections.
- Checking for damage to clamping structures.
