Modern winding deformation testers integrate high-speed signal processing and intelligent analysis software with powerful functionality
Function/Parameter Description and Significance
Sweep Frequency Technology Uses DDS (Direct Digital Frequency Synthesis) technology to generate high-precision, high-stability sine wave sweep signals.
Measurement Range Mainstream instruments typically have a frequency sweep range of 1kHz - 1MHz, with some high-end models extendable to 2MHz to cover more comprehensive winding information.
Measurement Accuracy Amplitude measurement accuracy can reach ±0.1dB, with frequency accuracy better than 0.01%, ensuring capture of subtle winding changes.
Sampling System Equipped with dual-channel 16-bit high-precision A/D sampling, one channel collecting the excitation signal and one collecting the response signal for transfer function calculation.
Intelligent Diagnosis Built-in expert diagnostic system capable of automatic horizontal comparison (between three-phase windings) and vertical comparison (with historical data), providing reference conclusions on deformation degree (such as normal, mild, moderate, severe deformation).
Efficient and Convenient Single-phase test time is typically less than 60 seconds. The testing process does not require transformer lifting or disassembly, greatly improving inspection efficiency.
