Three-Phase & Single-Phase Transformer Winding Frequency Response Analyzer

1. Winding deformation test based on different standards of sweeping
frequency
method.
2. It can measure the phase frequency curve and amplitude frequency curve of
each winding of the transformer.
3. It can cyclically test of phase and amplitude of transformer windings at
fixed frequency.
4. Analyze the transformer amplitude-frequency curve based on IEC standard.
5. Built-in non-dropout memory, winding deformation can be saved for 40
groups.

1. Sweeping frequency method to measure winding deformation.
