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)
