Actually guys, it is not a fuse per say, it is fed from a circuit breaker. Not the kind found in the home either. Most likely there was a stuck breaker which DOES happen. And from the video I would venture to say it was a 69Kv primary at least. My employer (The Board of Public Utilities in Kansas City Kansas), Had a lightning strike hit one of our 161kv/69kv transformers and it took them about 9 hours to put the fire out. The insulating oil has a high flashpoint, but when it does catch fire....look out Chuck K0XM Lead Substation Technician (25 Yrs)

More than likely the fusing was proper. Typically substation transformer size along with fusing is coordinated and engineered rather extensively. My suspicion is that a component failure may have contributed to the total failure of the transformer. It is possible the a fuse did open, but that the fuse holder assembly could have failed in such a way that an arc continued the current flow regardless of the open fuse. It would be interesting to know exactly what did happen. Chuck WB2EDV Yahoo!
