CHONGQING GOLD
9031809090
GDRZ-902 Fast Scan FRA Tester Transformer Winding Deformation Analyzer IEC60076-18
Reference Standard
IEC60076-18: Power transformers - Part 18: Measurement of frequency response
Advantages of our GDRZ-902 Transformer FRA Tester:
1) High precision diagnosis: The GDRZ-902 FRA tester adopts advanced signal processing algorithms to sensitively capture subtle deformations of windings, locate fault points, and provide reliable basis for preventive maintenance.
2) Custom scanning: 10Hz~10MHz, with a maximum of 4000 scanning points.
3) GDRZ-902 FRA Tester can measure the phase frequency curve and amplitude frequency curve of each winding of the transformer;
4) Transformer FRA Tester can cyclically test of phase and amplitude of transformer windings at fixed frequency;
5) Efficient and portable: Integrated design, supports on-site testing, eliminates the need to disassemble transformers, significantly reduces testing time, and improves operation and maintenance efficiency.
6) Intelligent analysis: Built in professional software automatically generates visual reports to assist in determining the health status of windings and reduce human errors.
7) Widely applicable: Compatible with transformers of different voltage levels and capacities, meeting the needs of multiple scenarios such as power plants, substations, and industrial electricity.
8) Equipped with an automatic wide paper micro printer: After the experiment is completed by GDRZ-902 Transformer FRA Tester, the test results can be printed using the device's built-in micro printer to obtain curves and data.
