IEC 62368 Partial Discharge Tester

CS19010 Series Partial Discharge Tester IEC62368 G.5.4 Compliant High Voltage PD Testing Equipment

The IEC 62368 Partial Discharge Tester enables manufacturers and testing laboratories to evaluate the insulation integrity of high-voltage components such as optocouplers, digital isolators, IGBTs, MOSFETs, and insulating substrates used in AV/IT equipment. It performs sensitive partial discharge measurements according to IEC 62368-1 G.5.4.

This high voltage PD testing equipment is essential for ensuring that insulation systems can operate safely without dangerous partial discharges, supporting product development, quality assurance, and regulatory compliance in the audio, video, and information technology industry.

Technical Parameters

Professional Construction & Technical Precision

The IEC 62368 Partial Discharge Tester features a stable high-voltage generation system paired with a highly sensitive PD detection module. It utilizes precision control circuits and calibrated measurement channels to reliably detect partial discharge signals as low as 1 pC, delivering excellent repeatability and accuracy required for insulation evaluation.

The modular design, combined with programmable test parameters, allows flexible configuration for different high-voltage components such as optocouplers, isolators, and substrates, while maintaining consistent performance to meet the stringent requirements of IEC 62368-1 G.5.4.

Testing Principle

The tester applies a gradually increasing AC high voltage to the component while continuously monitoring for partial discharge signals within the insulation. According to IEC 62368-1 G.5.4, any partial discharge must remain below specified limits to ensure long-term safety and reliability of AV/IT equipment.

By precisely measuring both the magnitude of partial discharge (in pC) and leakage current, the system helps identify hidden insulation defects, micro-voids, or material degradation that could eventually lead to dielectric breakdown or safety hazards under real operating conditions.

Common Error Mitigation

To obtain accurate and consistent test results, the following practices are recommended:

• Use the PD calibrator to verify system sensitivity before testing.
• Ensure proper shielding and grounding to reduce external interference.
• Follow recommended voltage ramp rates and hold times as per IEC 62368-1 G.5.4.
• Maintain stable laboratory temperature and humidity during testing.
• Regularly inspect high-voltage connections and cables for optimal performance.

Applications & Use Cases

The IEC 62368 Partial Discharge Tester is primarily used by AV and IT equipment manufacturers and component suppliers to verify the insulation quality of high-voltage parts such as optocouplers, isolators, IGBTs, and MOSFETs.
