Original Japan HIOKI ST9210 AC Partial Discharge Sensor, Max 5kVrms /7.07kVpeak AC PD Test Unit Exclusive Matching Accessory For ST4200 Partial Discharge Detector & 3153 AC Hipot Tester

ST9210 AC partial discharge sensor is a core front-end sensing device for AC partial discharge testing, perfectly matched with HIOKI ST4200 partial discharge detector and 3153 AC withstand voltage teste

It integrates internal blocking coil and coupling capacitor to extract tiny partial discharge charge signals from high-voltage test loops, fully compliant with international standard IEC 60270 for motor winding PDIV (Partial Discharge Inception Voltage) testing. Max withstand input voltage reaches 5kVrms /7.07kVpeak, fully meeting the high-voltage test requirements of 800V new energy vehicle drive motors, transformer windings and insulating materials. It can be used independently in laboratory R&D test benches and mass production line automatic inspection equipment.
