GDRZ-903 Transformer Sweep Frequency Response Analyzer (SFRA and Low-voltage Short-circuit Impedance)

GDRZ-903 Transformer Sweep Frequency Response SFRA Analyzer can use two methods to detect the deformation of the transformer at the same time. One is the sweep frequency response analysis method, the other is low-voltage short-circuit impedance method. Using two methods can effectively reduce incorrect judgments. The tester, follow the national power industry standards DL / T911-2004 and DLT 1093-2008, and can be used for IEC60076-18-2012 and IEC60076-5-2006.
