The ST4030A is an impulse winding tester, or surge tester, that combines the functions of both a resistance meter and insulation-withstand testing required for electric motor winding manufacturers to improve quality. Meet the needs of more reliable motor windings in light of the increasing use of electric vehicles and self-driving technology.

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)

Product Warranty Period: 1 year
