2012-08-02Distributed 380kV cable temperature monitoring and rating (TenneT TSO B.V.)
TenneT has installed the 380kV high voltage connection 'Randstad380', which is a 380 kV high voltage connection including cables. Although several 380 kV cable projects have been realized in Europe, the operation experiences of this kind of cable in meshed networks are very limited in general. Operation time is relatively short and behaviour of this kind of cables in 380 kV transmission systems is not clear. Therefore, TenneT has defined a research program in which the behaviour of long 380 kV cable …

2012-06-01Powercable connection monitoring system (TenneT TSO B.V.)
Powercable connection monitoring system for 380kV high voltage cable. Several 380 kV XLPE cable projects have been realized in Europe, the operation experiences of this kind of cable in meshed networks are however very limited in general. Operation time is relatively short and behaviour of this kind of cables in 380 kV transmission systems is not clear.
TenneT has asked to proof the theoretical models on system level using off-line or on-line measurements. To be able to measure a monitoring/measuring …

2012-04-05Remedial burial activities NorNed HVDC cable in Eems/Waddenzee area (TenneT TSO B.V.)
Remedial burial activities to increase the protection of the NorNed HVDC cable in the Eems and Waddenzee along the cable route from KP 0.0 to KP 40.0. Target burial depth is 2 meters and at certain areas 3 meters. Preference is that activities are executed while HVDC cable connection is in operation at + 450 kV DC and - 450 kV DC.
The NorNed HVDC cable, constructed in the period from 2006 to 2008, consists of a two core HVDC connection between the Netherlands and Norway. The area between KP 0.0 (the …
