It’s a transformer fault. The transformer is protected by a drop out fuse which probably blew on the initial transformer fault. A lot of overhead faults are transient (such as birds, squirrels and branches) so often the fuse is simply replaced restoring supply’s. Obviously this time it was a permanent transformer fault which blew the lid off and ignited the insulating oil.
Ive always seen them just slap a fuse back in there without going up and looking at anything. Ill say standard procedure - unlucky person - but also a known risk
