1 Field Experiences Partial Discharge Diagnosis on MV Cables Philipp Legler Technical Support Applications Engineer (Megger Site Germany) XVI. Szigetelésdiagnosztikai Konferencia ( , Sümeg)
2 Introduction Reasons of Cable Faults Most of them are Workmanship Failures Predominantly caused by Service Contractors (Man Power & Time issued) Main Reasons are Time Pressure - need to do xx Joints a Day (mostly caused by Purchase Department) Joint Hole not large enough Especially in Cities: to much other Cables / Pipes Climatic Conditions Not having the Skills / Certificates 2
3 Case Study No. 1 Operator: DREWAG Test Object: 12/20 kv & only XLPE insulated Cable Length: 367 m Joint Type: Tyco MXSU 5131 Measurement History: (only Phase L2) PD Diagnosis with OWTS 3
