As many of you might know we had a bad snow storm here in the Southern NY area Thursday and Friday of last week. Wet, heavy snow. Lots of downed trees and lines.
Friends of my wife who live down the street call her on Friday AM to say they are without power. The story goes that a lamp bulb flashed and exploded, the lamp smoking almost starting a fire as their power went off. At the same time they see a flash then hear an "explosion" from outside. They call the fire department who respond. They find no fire and used a thermal imaging device. They turned the main breaker off in the old Zinsco panel and left.
Next day my wife tells me the story and my opinion is that a primary (12.5Kv around here) came down and crossed with the secondary distribution someplace. That's what the "explosion" and flash was and that's why the lamp burned. I mention that they will be very lucky if any of their electronics and appliances survived.
A day or so later the power company still hasn't gotten to them and out of curiosity I take a ride to see where their distribution comes from. A couple of blocks away I found a primary down with the top leg of the open wire secondaries burned and also lying on the ground.
So last night the power company finally gets to them. Their lineman probably working 24 hour shifts apparently put the lines back together and they are at the house. Seems they found that the meter electronics fried (we have RF remote reading meters here) but it still passed current. Friend says that the lineman didn't want to go into the house because of the dog so they asked the friend's husband to go turn the main on. He does and the panel starts burning, so he shuts it off. At that point my wife's friend calls and asks if she would ask me to come by and talk to the linemen, which I do.
Now I realize that these are linemen not electricians. I fill them in on how there was a 12.5Kv cross, that's why the meter was fried. I went in and looked at the panel. Without removing the cover I saw that the paint on the front cover was burned off and the plastic blanks and some breakers were melted or burned. At that point they were running a new drop and I asked them not to energize it- the customer has to have an electrician replace the service and do whatever else needed to be done, file for it and have it inspected. The lineman opted to leave the drop disconnected at the street, they left the old meter in the pan and bugged the new drop to the old service.
Since I no longer do electrical work I offered to call a friend of mine who is an EC to see if he can get there first thing in the AM. Husband is a bit of an odd ball and he refuses, he will get somebody else. OK. Sitting there in the cold and dark for the last five days wasn't enough. Now I figure he want's to shop around.
Well, he did get somebody else- another local EC. This guy tells the husband that he needs the power company to energize the old service before he can do anything. I assume he looked at the condition of the panel. I'm thinking that he is trying to avoid filing and an inspection. I hope the power company is smart enough to refuse.
