1.1 Transformer winding deformation testerMain technical features

l pickuseThe sweep frequency method is used to measure the characteristics of transformer windings without lifting or disassembling the transformer cover,By detecting the amplitude frequency response characteristics of each winding6kVAnd above transformers,Accurately measure the distortion, bulging, or displacement of the winding.

l Fast measurement speed, with a measurement time of less than 3 minutes for a single winding.

l The frequency accuracy is very high, with an accuracy of over one thousandth.

l Digital frequency synthesis provides higher frequency stability.

l 5000VVoltage isolation and sufficient protection for testing computers.

l It can load 9 curves simultaneously, and the relevant parameters of each curve are automatically calculated to diagnose the deformation of the winding and provide reference conclusions for diagnosis.

l The analysis software has powerful functions, and the software and hardware indicators meet the DL/T911-2004 standard.

l The software management is highly user-friendly and intelligent. After setting the parameters, all measurement work can be completed with just one key press.

l The software interface is simple and intuitive, with clear menus for analysis, storage, report export, printing, and more.
