LDRZ-2001 Transformer winding deformation tester is a professional testing equipment that adopts advanced Frequency Response Analysis (FRA) technology, carefully developed by Wuhan Longdian Electrical Equipment Co., Ltd. This tester is designed specifically for detecting and analyzing the deformation of internal windings in 63kV to 500kV power transformers. By measuring the response characteristics of transformer windings at different frequencies, it can accurately determine whether the windings have twisted, bulged, shifted, tilted, inter turn short circuits, and other faults. LDRZ-2001 adopts high-speed dual channel 16 bit A/D sampling technology, combined with high-performance digital signal processing technology, to ensure the accuracy and reliability of test results. At the same time, the tester is equipped with a user-friendly interface and powerful data analysis software, making the testing process more convenient and efficient.
