IEC60076-18 Single-Phase & Three-Phase Transformer Winding Sweep Frequency Response Analyzer

A. Winding deformation test based on different standards of sweeping frequency method.

B. Measure the phase frequency curve and amplitude frequency curve of each winding of the transformer.

C. Cyclically test of phase and amplitude of transformer windings at fixed frequency.

D. Analyze the transformer amplitude-frequency curve based on IEC standard.

E. Built-in non-dropout memory, winding deformation can be saved for 40 groups.
