The MICROTEST 7713 is an Impulse Winding Tester delivering pulse voltage outputs from 200V to 10000V. It uses damping attenuation waveforms generated by L/C resonance to analyze magnetic components for defects, such as short circuits between coils or winding wire layers. Designed specifically for Inverter-Transformer products, this model supports high-frequency harmonic and noise analysis. By amplifying the waveform through high-frequency resonance, it accurately detects insulation defects caused by high-voltage coil slot leakage. The tester provides various comparison modes, including total area comparison, area difference comparison, corona count comparison, jitter count comparison, and waveform comparison, enabling precise identification and detection of faulty products.
