  Most failures in electric power cables are attributed to the development of water trees inside the insulating materials. Thus, the development and utilization of Tree Retardant Cross-Linked Polyethylene (TR-XLPE) based cables have recently been given great attention to overcome the treeing issues. TR-XLPE cables use low-density polyethylene compounds suppressing the formation of water trees while retaining excellent electrical,...

  This paper is focusing on 3D Finite Elements Analysis (FEA) based modelling of protrusions as defects or imperfections in the XLPE high voltage cable. This study is aiming to examine the impact protrusions have on the initiation of partial discharges. Spherical and ellipsoidal protrusions with different sizes at the conductor screen of the high voltage cable is an essential content of this paper. In addition, a spherical gas-filled...

  - Year 2005

  W pracy omówiono czas inkubacji i wzrostu drzewka elektrycznego rozwijającego się w izolacji polietylenowej usieciowanej w układzie ostrze - płyta uziemiona. Badania przeprowadzono przy udarach łączeniowych nałożonych na napiecie przemienne (napięcie skojarzone). Wyniki badań wskazują na istotny wpływ ładunku przestrzennego wprowadzanego napięciem udarowym na inkubację i propagację drzewienia elektrycznego.

• Measurement methods for assessing insulation condition of underground pipelines

  Publication

  - Ochrona przed Korozją - Year 2013

  The paper discusses the most frequently applied measurement methods for assessing the quality of external insulation along pipelines and detecting defect locations in the protective coating. The quality of coating along a given pipeline section under investigation is assessed by determining unitary resistance of the coating, which is calculated on the basis of measurement results obtained along a pipeline subjected to cathodic...

  - Year 2021

  This paper investigates the treeing phenomenon in polymeric materials such as crosslinked polyethylene (XLPE) that is widely used in medium and high voltage power cables as primary insulation. The modeling of electrical tree growth in the insulation from its initiation to breakdown is significant research work that illustrates the discharge dynamics and its impact on aging process in polymeric insulation. This study utilizes pulse...
