Sammendrag
This paper considers the problems with induced currents
in copper screens and aluminium laminate, consequences
and improvements for a 24 kV watertight XLPE cable
system. Repeated faults on a heavily loaded new cable
system installed for the generators of a Norwegian
hydropower generation station resulted in serious doubts
about the performance and life expectancy of the installed
system. At times during the project, a full replacement
with new cables was seriously discussed. The costs
involved would; however, be substantial. Hence a team
consisting of parties involved was set up with the aim to
try to come up with a reliable solution to avoid
replacement of the cable system.
