Troubleshooting and testing of HV cables

Testing and analysis of high voltage cables requires both knowledge and experience. Rohde Consulting can assist with both. The course is a good start to understand the many possibilities and approaches. Call us to learn about the many options.

01. Intro Cable test and analysis

Cable analysis techniques hold many possibilities, which are becoming more common, even with several applications, for example, within generators and transformers. This course covers two major areas: Testing and Analysis. In the analysis portion, several different techniques that should be used and can obtain an state based maintenance paramenter for cables. The methods require both knowledge and experience.

02. Partiel discharge & measurement technique

Instructors will review cable types and typical failures, like water penetration (Water trees), and illustrate partial discharge (PD). Studens will learn relevant standards for cable testing in the voltage levels from 10 kV to 150 kV. The course will provide a thorough examination of reflection theory and VLF 0.1 Hz sinus, including Tan Delta Diagnosis.

03. HV cable measurements

Studens will analyse cable measurements in cases studies, including cable set analysis, and will asses and locate PD is present. Students will evaluated Tan Delta Diagnosis and prepare work procedures as well as built test setup for noise analysis.

04. Qualifications after the cable course

Deltagerne får kendskab til fordele og ulemper af måleteknikkerne. Man kender fremgangsmetoderne og kan give en kvalificeret vurdering af kablets tilstand. Kursisten kan udføre kabeltest og fejldiagnosticering. Der bør efterfølgende indsamles data fra ens leverandør af muffer, kabler mm. for at kunne give et kvalificeret tilstandsbillede.
