Transformer Winding Deformation Tester is designed to assess and analyze the winding deformation in power transformers rated 6kV and above. This advanced instrument uses the frequency response analysis (FRA) method to detect winding deformations caused by faults such as inter-turn short circuits, coil displacements due to electromagnetic forces, and mechanical impacts during transportation. By comparing frequency response curves, it accurately determines the extent of transformer deformation.

Features

  • Compliance with Standards: Adheres to the DL/T911-2016 standard for frequency response analysis of power transformer windings.
  • Dual Power Supply: Operates on both AC power (100V-240V) and a 7.5V lithium battery, with automatic switching and battery charging features.
  • Integrated Design: Combines measurement control and display in one unit, minimizing the need for additional accessories.
  • High-Speed Processing: Utilizes a high-speed microprocessor and advanced DDS sweep technology for fast and accurate testing.
  • Advanced Display: Features an 8-inch resistive color touch screen with adjustable brightness for clear and easy operation.
  • Extensive Data Storage: Can store up to 210 sets of data, each containing three curves for comprehensive analysis.
  • Data Management: Includes USB and WiFi connectivity for easy data transfer and remote testing.
  • User-Friendly Software: Accompanied by powerful PC software for data analysis, report generation, and word report export.
