The Western HVDC Link

Alan Capon
I did originally answer the previous thread, but have since deleted my response and I believe a new thread with a proper and correct title is the correct way of answering. 


More info on the fault here: https://www.energy-reporters.com/transmission/italys-prysmian-under-fire-over-uk-interconnector-failure/ 


Reports suggest an undersea cable fault in the vicinity of Liverpool Bay. 


Regards,


Alan.

    It should be remembered that this scenario is nothing like just turning an mcb back on to see what happens. The voltage is 600kV DC and the normal load rating is 2,200MW. Bearing in mind the cost of the asset (the cable plus its two converter stations), and the possible effects of placing a direct short onto the supergrid network, it must be proved beyond reasonable doubt that no fault is present, before the cable and its associated substations are re-energised. As part of proving no fault exists, the exact reason  for the trip must be identified.
