Frequency Response Analyzer HYRZ-903
Our company has designed the frequency response analyzer HYRZ-903, which 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.
