NDBRY-Ⅲ Series Winding Deformation Tester-Wuhan Nanxing Electric Power Technology Co., Ltd.

The hardware movement adopts DDS Dedicated digital high-speed frequency-sweeping technology ( United States ), Testing can accurately diagnose faults such as winding distortion, bulging, displacement, tilting, inter-turn short circuits, deformation, and phase-to-phase contact short circuits.

High-speed dual-channel 16 position A/D Sampling ( On-site testing involved modifying the tap changer, resulting in a noticeable change in the waveform. )。

Signal output amplitude is software-adjustable, with a maximum peak amplitude. +10V.

The computer automatically analyzes the detected data and generates electronic documents for storage and printing.

The instrument features a dual measurement system, supporting both linear sweep and segmented sweep measurements. , It is compatible with the measurement modes of the two prevailing technical schools currently used in China.

The amplitude–frequency characteristics comply with the national technical specifications for amplitude–frequency characteristic testers. The horizontal axis ( Frequency ) It features both linear and logarithmic scales.

Accordingly, the printed curve can be either linear or logarithmic; users may select the appropriate type based on their specific requirements.
