I considered that. Considering the cheap cost of the cable, the best solution appears to simply be 'dont have a breaker'. In either over current or over voltage conditions, simply sacrifice the cable.
Obviously you engineer the convertor stations to minimize the chances of that happening - stopping the convertors automatically if anything looks abnormal. The cable has sufficient capacitance that you have multiple milliseconds to respond, so automated systems should have no difficulty.
- gwbas1c 1y ago> simply sacrifice the cable How is that different from a fuse?
- londons_explore 1y agoIf I said to build a 3000 kilometer fuse and quench it with the entire Atlantic ocean, people would tell me I was being silly.
- gwbas1c 1y agoBut given how expensive the wire will be to lay, what about an actual fuse that's cheaper than laying a whole new wire?
- Dylan16807 1y agoHow much cheaper, and what are the odds of needing the fuse? If it's cost effective then go for it. But the specific thing they're skeptical about is whether a 14MV 750A fuse will be cheap enough.
