HDRB-II transformer winding deformation of the main technical characteristics of the tester: 
 ? Wrong transformer hanging hood, removable case can be tested. 
 ? Use the most popular sweep method to measure 
 ? The instrument can be measured on more than 6kV transformer 
 ? Split structure between the test host and the host computer using a USB connection, plug and play 
 ? Field wiring is simple, easy to use 
 ? Wide dynamic range:-100dB to 20dB 
 ? Analysis software, powerful, software, hardware indicators meet the GB DL/T911-2004 
 HDRB-II winding deformation tester used to test the 6kV and above voltage grade power transformers and other special purpose transformers, power transformers in operation or during transport inevitably have to suffer all kinds of fault short circuit current shock or physical shock, short circuit The current generated by the powerful role of electric power transformer windings may lose stability, lead to local distortions, drum kits or displacement of permanent deformation, so that will seriously affect the safe operation of the transformer. DL/T911-2004 according to the national electricity industry standards using frequency response analysis measurement of transformer winding deformation detection of transformer winding the amplitude frequency response characteristics, and test results for vertical or horizontal comparison, according to the amplitude-frequency response characteristics change extent, determine the transformer winding deformation that may occur. 
 HDRB-II transformer winding deformation tester consists of the measurement part and the analysis software part, the measurement part of the composition of the black box, by the signal generation and signal measurement and analysis in part by the laptop computer to complete the measurement part is connected via USB with a laptop, also can be wired or wireless Ethernet connection.
