Hioki-ST4030A IMPULSE WINDING TESTER
Diagnose the Insulation Quality and Deterioration of Rotor Windings while in Assembled State via Response Waveform Quantification
Key Features and Functions
- 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)

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.
Basic specifications
- Measurement items:
- Quantification (LC value, RC value) of the response waveform obtained when impulse voltage is applied, pass / fail judgment
- Waveform judgment using AREA value, Flutter, Laplacian etc.
- Equipped with dielectric breakdown voltage test function
- Applied voltage:
- 100 V to 3300 V (Setting resolution: 10 V steps)
- Maximum applied energy: approx. 55 mJ
- Testable inductance range: 10 μH to 100 mH
- Sampling: 200 M / 100 M / 50 M / 20 M / 10 MHz, Resolution: 12 bits, Number of data: 1001 to 800 points (1000 point steps)
- Voltage detection accuracy: [DC accuracy] ± 5% of setting, [AC band] 100 kHz: ± 1 dB
