Abstract:
In HVDC power transmission, power cables are
taking the place of overhead lines at a rapid rate. While testing
HVDC power cables, manufacturers often encounter difficulty
of handling, as a prior knowledge of the time at which the power
cable would discharge completely is not known. This paper
explores the discharging time of cables of different lengths and
also analyzes the factors which affect the discharging
phenomenon, and tries to give a proper time after which a tested
cable can be handled safely. The complexity arises because of
the fact that a cable behaves as a distributed parameter
transmission line. The discharging phenomenon has been
simulated using PSPICE software and also some of the results
are verified analytically
