САЖЕТАК / ABSTRACT:

To prevent or at least minimize circulating currents in cable sheaths, single point bonding or cross bonding can be implemented along the cable route. The open ends as well as the cross-bonding points should be protected against slow- and fast-front overvoltages by suitable sheath voltage limiters (SVLs). SVLs are installed in link boxes at joint bays, either underground or above ground depending on the location of the cable joints, as well as at terminations. The main criteria for selecting SVLs is the sheath to earth voltage. This paper presents comparison of criteria for the selection of SVL in accordance with the following documents:

  • IEC 60099-5: Surge arresters – Part 5: Selection and application recommendations [1]
  • Electra 128-2: Guide to the protection of specially bonded cable systems against sheath overvoltages [2]
  • CIGRE TB 283: Special bonding of high voltage power cables [3]
  • CIGRE TB 797: Sheath bonding systems of AC transmission cables – Design, testing, and maintenance [4]
  • ENA Engineering Recommendation C55 Insulated sheath power cable systems [5]
