No mechanical deformation or winding damage during 160ms faults
3. Signal Integrity
≤3% waveform distortion (vs. industry-standard 5%)
Stable output under capacitive loads (e.g., test object discharge)
4. Industrial Durability
Full-power operation for 60 minutes
Reinforced windings resist thermal stress
Safety & Design
