I'm very suspicious of this, because it would also imply 10x overcurrent on the associated transmission gear. There's limits on how much you can overcurrent a transformer before the core magnetically saturates, for example. Also I would expect protection systems to trip out at such a huge divergence from rated current. Do we have a citation?
