Excuse my words, I am so upset … I give you my story. My name is Lothar Schmitz, I am 39 and my job is Service electrical maintenance Manager. Our main customers are large industrial sites.
We had a shortcircuit in one of our substation of our network: one 10kV high voltage fuse melted. A guy of my team quickly reached the site and changed the blown fuse and re energized the feedind circuit …
Two weeks later, same problem occurred in the same cubicle but this time it’s the other phase fuse which blew up because in fact it has been damaged at the time of the first fault.
My agent of course did come back and decided to replace the 2 other high voltage fuse s … unfortunately during the mounting, he broke one fuse down, had to clean the substation floor.
This little incident was becoming a real big problem because he did not have any other in stock and with a downstream production with no energy !
* 1,5 man day lost
* Communication problems linked with production losses
* Penalties due to the customer of 11500€
Now, you understand why I am upset about high voltage fuse and this is not the fist time. I don’t think I am the only one and I propose to share our experiences. Please use the comment area below …
