This technical webinar will explore advanced strategies for locating partial discharges (PD) on critical electrical assets as transformers, GIS substations, HV & MV cable terminations and switchgears with special focus on the application of Transient Earth Voltage (TEV) detection methods.

TEV sensors are a powerful, non-invasive tool for localizing partial discharges, especially in assets in which there is needed to find any possible defect in a specific enclosed area. However, its effectiveness depends on the asset type, environmental conditions, and integration with complementary diagnostic methods.

The session will provide practical insights into when and why TEV sensors is a valuable tool in the PD localization process.

Key topics covered

Understanding Partial Discharge (PD):

  • A brief refresher on what PD is, its causes, and the risks it poses to electrical infrastructure.

Detection vs. Localization:

  • The distinction between detecting PD presence and pinpointing its exact location within our mixed hardware + software solution.

TEV technology explained:

  • How TEV sensors work and what they measure.
  • Advantages of TEV sensors in detecting PD defects on critical assets.
  • Limitations and scenarios where TEV may not be effective.

When is TEV most useful?

  • Ideal conditions for TEV application (e.g., metal-enclosed switchgear, dry environments).
  • Case studies demonstrating successful PD localization using TEV.
  • Integration of TEV with other diagnostic tools like ultrasonic and UHF sensors.

Best practices and troubleshooting:

  • Tips for interpreting TEV signals, avoiding false positives, and ensuring accurate localization.

Q&A

The session will be concluded with an interactive Q&A.
