Internet of power- Digital circuit breakers.

I don't really see that as anything more than a very reliable solid state relay instead of contacts, and at the moment such a thing would be expressly prohibited from performing any safety function in the UK regs.

537.2 Devices for isolation

.....

537.2.2 Semiconductor devices shall not be used as isolating devices.

I must admit that it has occurred to me many times recently  with the high voltage silicon carbide devices, that one could make a circuit breaker that opened in much less than a microsecond, completely changing the nature of the adiabatic assumptions.
