Delayed effects of lightning damage

Delayed effects of lightning damage

Delayed effects of lightning damage

(OP)
One of my customers sustained lightning damage on some equipment recently. He has some equipment that is no longer functioning properly after a lightning strike, but which shows no physical damage. The insurance company is hesitant to pay for the repair of the equipment because they cannot see any evidence of damage. Basically, all I am looking for is a statement from a qualified and trained individual, that lightning can damage electronic circuits without showing such physical evidence, and that failure of these electronic circuits can show up after the initial strike. (Anyway, that is what I understand about lightning damage).
 
Assuming this is true, can someone here, preferably an electrical engineer or P.E. compose a short statement to support our position, so that the insurance company will cover the replacement of the electronics in his machinery?
 
Thanks / 73,

RE: Delayed effects of lightning damage

What you are asking for usually requires a contract and compensation. References to articles and professional opinions are abundant on this forum, but don't forget that they are worth exactly what you pay for them.
Contact a Professional Engineer and get a written and stamped professional opinion, which will certainly be more impressive to your insurance company than some comment on an online forum.

RE: Delayed effects of lightning damage

I agree with DanDel. See if you can find a PE who specializes in Power Quality issues as well. They focus specifically on the damage that occurrs from surges and noise, for which lightning is the extreme case of both. If you do a search on the term "Power Quality" you will get hits on a number of trade journal websites that often have listings of professionals in your area. Just make sure they have a PE stamp, the insurance compnanies find it hard to argue with that.
