IMPULSE WINDING TESTER ST4030 Diagnose the Insulation Quality and Deterioration of Rotor Windings while in Assembled State via Response Waveform Quantification Overview The ST4030 is an impulse winding 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 • - Diagnose defective insulation (pseudo-shorts) between motor windings by testing for microscopic partial discharges hidden in noise (option) Hioki ST4030 Impulse Winding Tester - Introductory Video The Impulse Winding Tester ST4030 identifies the LC and RC characteristics from the response waveform when a coil is measured. Because the circuit constant value can be treated quantitatively, users can clearly define the threshold values against which to determine the pass/fail condition of coils based on numerical data. In addition, because the test results are in numerical terms, data can be further utilized statistically as a method of quality control. Accumulated data from each fault can be fed back to upstream processes to predict conditions that would lead to non-compliant windings and contribute to the prevention of future defects.
