This happened in 1996.

Two of my former collegues, Andy and Ollie were working with repairs on electrical equipment in

facilities.

There was a tricky problem with an old transformer and a rectifier system. This system was not

the smallest one, comparatively big with a height of more than two meters and a width of several meters. Don´t comment on that you power station guy reading this.

However, after spending a week or so trying, sorry, identifying the problem and doing the necessary repairs they were preparde to restart the unit once again.

When that was to be done they showed up fully equipped with DVM´s and analyzers looking real

confident.

But when the main power was set the unit responded with a big fire flame coming out of the top

followed by a plume of nasty black smoke.

Ollie turned the power off again and turned to the scared-to-death crowd and said:

“You know what? I really guess we broke something this time.”

(But those guys are no longer my collegues.)
