Product Description

Product Description

KDZD Transformer Winding Deformation Tester is a high-precision instrument designed specifically for detecting and analyzing the condition of transformer windings. The instrument measures the frequency response or impedance characteristics of the transformer to identify irreversible damage, such as twisting, bulging, shifting, tilting, inter-turn short circuits, or phase-to-phase short circuits. By comparing the test data horizontally and vertically, users can accurately assess the degree of damage, including normal windings, slight deformation, noticeable deformation, and severe deformation.

Output impedance	50Ω
Measurement speed	about 50 seconds/phase (1MHZ)

Applications:
It is suitable for power transformers rated 66kV and above, as well as other special-purpose transformers.
 

Application Scenarios:

• Transformer operation maintenance and fault analysis in power systems.
• Regular inspection and condition assessment of power transformers.
• Performance monitoring and fault warning for special-purpose transformers.

Key Features:

• Frequency Response Analysis: Measures the transformer's frequency response to detect deformation.
• Horizontal and Vertical Comparison: By comparing the feature graphs of different states, the instrument accurately assesses the transformer's health status.
• Fault Analysis: Enables fault analysis of the transformer's operating condition, particularly useful for post-incident maintenance and repair.
• Routine Inspection: Periodically checks transformers in operation, saves frequency response graphs, and provides crucial data for future maintenance and fault analysis.

Product Advantages:

• High-Precision Measurement: Equipped with a 32-bit ARM chip and DDS frequency synthesis chip, coupled with a 16-bit high-precision A/D chip to ensure measurement accuracy.
• Fast Response: Quick measurement speed to rapidly obtain transformer status information.
• User-Friendly Operation: Features a large touchscreen LCD with an intuitive interface for easy operation.
• Compact Design: Small size, lightweight, and suitable for on-site use.
• Standalone and PC Connectivity: Can operate independently or be connected to a PC for data analysis and report generation.
