Portable Three-phase Frequency Response Analysis Transformer Sweep Frequency Response Analyzer For Power Equipment Quality Inspection
Product Description
GDRZ-902 Transformer Sweep Frequency Response Analyzer(SFRA)
|
Product Description
1）The GDRZ-902 Transformer Winding Deformation Tester (SFRA) is a high-precision professional instrument developed specifically for testing winding deformation of power transformers (three-phase or single-phase) in factory, handover, and fault tests. Based on the frequency sweep method and compliant with international standards such as DLT911-2016, GB/T-1094.18, and IEC60076-18:2012, it takes an ARM processor as the core for sampling, processing, and output.
2）Equipped with a color touch screen, English menu, high-speed thermal printer, and powerful data management functions, it can accurately measure amplitude-frequency and phase-frequency curves of transformer windings, providing authoritative data support for judging winding deformation degree in power laboratories.
