The ST9000 Discharge Detection Upgrade for the ST4030 Impulse Winding Tester provides detection enhancements to spot discharge that is buried in noise.
• Option additional function for ST4030
• Detect microscopic partial discharges obscured by noise to determine defective insulation (pseudo-shorts)
• HIOKI original filter * (*Noise components within the high frequency components appearing within the entire response waveform are removed to extract only the partial discharge component in order to make a pass/fail determination. Jointly developed with Aisin AW Co., Ltd.)
• Peripheral equipment (antenna for discharge detection etc.) not required to easily detect discharge
