PD SENSOR ST9210
PD sensor for AC partial discharge (AC PD) testing
NEW
Partial Discharge Sensor Optimized for AC Partial Discharge Testing
The ST9210 is a partial discharge sensor designed for use in partial discharge (PD) testing during product development and production-line inspections of motors, insulation components, and other high-voltage devices. It supports AC PD testing using high-voltage AC sources and can handle input voltages up to 5 kV rms/7.07 kVpeak. The ST9210 is ideal for applications requiring high test voltages, such as EV motors, ensuring reliable and accurate discharge detection.
Key Features
- Detects partial discharges on waveforms up to 5 kV rms/7.07 kVpeak
- Works with the ST4200 Partial Discharge Detector for reliable partial discharge detection
- Compatible with various AC high voltage sources

Designed for stand-alone use in ACPD testing during R&D and pilot production
Maximum Input Voltage: 5 kV rms/7.07 kVpeak
Compatible Partial Discharge Detector: ST4200-50
Compatible AC High Voltage Sources: 3153, or third-party voltage sources (hipot testers)
The ST9210 enables AC partial discharge (AC PD) testing when used in combination with the ST4200-50 Partial Discharge Detector and an AC high voltage source. It supports discharge detection up to 5 kV rms/7.07 kVpeak and can be paired with your existing AC high voltage source (such as a withstand voltage tester). Ideal for creating a test environment in the development and evaluation stages before full system integration.
