Frequency Response Analyzer HYRZ-902
Transformer frequency responce analyzer is a high-precision instrument specially developed by our company for power transformer (three-phase or single-phase) factory, fault and and measurement of winding deformation, no-load and load loss parameters in the handover test. The instrument is small in size, light in weight, easy to carry, and extremely convenient to use on site, greatly reducing the labor intensity of testers and improving work efficiency.

2. Equipped with high-speed thermal printer, designed with storage function, convenient for data storage and printing.
3. Winding deformation test based on different standards of sweeping frequency method.
4. It can measure the phase frequency curve and amplitude frequency curve of each winding of the transformer.
5. It can cyclically test of phase and amplitude of transformer windings at fixed frequency.
6. Analyze the transformer amplitude-frequency curve based on DLT911-2016.
7. Built-in non-dropout memory, winding deformation can be saved for 40 groups.
1. Sweeping frequency method to measure winding deformation.
