It utilizes damping attenuation waveforms generated by L/C resonance to analyze magnetic components for defects such as short circuits between coils or between layers of winding wire. This model is specifically designed for Inverter-Transformer products and supports high-frequency harmonic/noise analysis mode. By amplifying the waveform through high-frequency resonance, it can precisely detect insulation defects caused by high-voltage coil slot leakage. The tester also offers various comparison modes, including total area comparison, area difference comparison, corona count comparison, jitter count comparison, and waveform comparison.
