Have you ever heard a decent size transformer blow when it can be bloody loud. Had one go and not sure what had happened when it woke me from sleep. Not always caused by just age, this transformer went due to a possum looking for a warm spot to camp.It was a transformer that exploded apparently. Really nothing to blink an eye over. Old transformers explode "all the time.". prob not mussles. And if someone wasted their zero days and their social engineering opprotunities on a transformer, they are a terrible hacker who wouldnt be able to do that in the first place.
