    Don't F**K with lightining its the real deal

    We were doing a seismic upgrade on the roof of one of our buildings 2 summers ago in late June (SF bay area) when that one freak early summer storm rolled in and it turned into a good thunder and lightning storm. The building housed a server farm for one of the cell providers (huge power loads) and we had done a pretty thorough job of covering the roof in preparation. However as the weather forecast started to get really nasty I called a bunch of guys in to make sure we were going to be good. We had just got there (9pm) and I was climbing the ladder and all of the sudden it appeared the transformer blew up, I mean BLEW up, I was at the top of the ladder maybe 100 feet away and my first thought was oh S**T water got in the switch gear and we just blew the place up $$$$$$$. The two onsite back up generators kicked on and the frenzy started. Once the sun came up we saw that lightning had hit the bus ducting and blew an 18" hole right threw it and took the t former with it. Lightning aint no joke!

        Some years ago I noticed a basketball size hole through the side of the roof of a little barn building in the backyard. I go in to look around and see nothing but splintered wood with burnt ends. Look closer and see charred branches on the tree next to it. Best I could figure was it hit the tree and jumped to the building. Lucky it didn't burn the building.

          Benjamin Franklin wasn't afraid of no lightening.

              We seem to have strikes close every year, but so far nothing directly on house. Last night there was one that hit a barbed wire fence 100 yds from me, I saw it hit Last year one hit close enough to roast my tv from the static. I generally hand inside now when a storm is rolling in.

                You think you're special just because your daddy didn't have a sister to be your mommy.

                  How high is the roof?
                  Is there a lightning protection system?
                  Horizontal bus duct on roof.... 🤪

                    Roof is 24'
                    No lightning protection, we very rarely get lightning.
                    Bus duct was at 3'+/- above ground level feeding from building main transformer to the building, up the wall 6'ish and thru the wall to the internal switch gear

                      Lightning keeps taking out the fuel station at works keypad login on/off functions. It's blown it up at least once a year if not more. They finally are looking in to Lightning protection for it.

                        That makes more sense. I bet the switchgear was a mess.

                          I'm imagining the company safety guy making him wear his NFPA70E insulated nomex suit, face shield, and rubber gloves/boots, because he's "working with switch gear", even though it's currently a slag pile of aluminum and copper.

                            Amazingly the main gear breaker tripped, the back up generators started up and the transfer switches switched over and they were back on line. The local utility swapped out the transformer 2 days later and temped them up on cabling. It took quite a while to get the new bus ducting installed. Could have been a whole lot worse. It definitely scared the shit out of me. I was sure we had caused it!

                              Think of all the guys that proved LIghtning was electricity before Franklin but we'll never know because they were struck dead on the spot.
