Key features
- Identify previously undetectable defects
- Detect waveforms with high precision (200 MHz high speed sampling × high 12-bit resolution)
- Identify single-fault turns via quantification of response waveforms into LC and RC values
- Diagnose defective insulation (pseudo-shorts) between motor windings by testing for microscopic partial discharges hidden in noise (option)
