    Besonderheit:

    1.Advanced DDS Core Technology
    Dedicated digital high-speed scanning (DDS) detects:
    Mechanical deformations (distortion/bulging/displacement/tilting)
    Electrical faults (inter-turn shorts, phase-to-phase contact faults

    2.High-Fidelity Acquisition System

    SoC-controlled architecture with MIL-spec components

    Dual-channel 16-bit A/D sampling (≥99.5% repeatability)

    Field Validation: Tap changer operations induce significant waveform deviations

    3.Dual-Sweep Measurement Modes
    Linear + segmented frequency analysis compatible with domestic technical standards

    4.Non-Invasive Testing Protocol
