The WDT-200 Sweep Frequency Response Analyzer is a powerful diagnostic tool for identifying mechanical issues inside power transformers without opening them. Using advanced SFRA (Sweep Frequency Response Analysis), the system applies a variable-frequency signal to detect changes in inductance and capacitance—key indicators of transformer damage such as winding displacement, shorted turns, and core movement.
Built for fieldwork, the WDT-200 is compact and self-contained, featuring a rugged case, a built-in PC for data processing, and robust software for visual diagnostics. It’s ideal for substation engineers and maintenance contractors looking for accurate and non-invasive transformer diagnostics.
Applications:
Detecting winding deformation, shorted turns, core displacement, and clamping faults
Preventive and corrective transformer maintenance
Post-transport transformer integrity assessment
Factory acceptance and routine in-service inspection
Power utility and transformer OEM testing programs
