PD diagnostics on medium- and high-voltage cables with the MPD series

Summary

Deepen your knowledge on the subject of partial discharge measurements on high-voltage cables. Familiarize yourself with the common software functionalities of the MPD system. Learn to identify and locate cable PD faults to better assess the condition of the asset. Get to know your measuring equipment better and deepen your knowledge through practical exercises.

Objectives

• Measuring partial discharges on MV/HV cables with the MPD 800
• Assessment of the insulation condition of MV/HV cables through PD measurements
• Monitoring the quality of the production process through measurements on insulation components
• Applying PD measurements for development and design of insulation components

 

Content

• ​​​​​​Overview of the most common defects in cable insulation, cable joints and cable terminations
• Typical causes of insulation aging (thermal, electrical, environmental and mechanical)
• Understanding the physics behind partial discharge measurements
• Performing cable PD measurements according to IEC 60270, IEC 62067 and IEC 60840
• Use of non-conventional measurement methods (e.g. inductive sensors)
• Perform Offline PD measurements on HV cables using practical exercises
• Synchronous and multi-channel partial discharge measurements for optimized test results
• Locating partial discharges in cables using TDR and STDR
• Learn about additional noise reduction techniques (Gating, 3PARD, 3FREQ)
• Interpret PRPD patterns and identify common PD defects for the cable insulation, joints and cable terminations
