Lightning Strike?

[UWEB]

Last night we had a heavy Thunderstorm here south of Hua Hin/Sam Roi Yot. Around 1.00 AM I heard a very loud bang and the Aircon went off for some seconds even with installed ESS.

This morning then I've checked the entire Electric System in my Buildings and found several MCB's and RCBO's tripped plus a total of 11 LED Downlights were blown and needs to be replaced.

As I have Surge Protectors installed in all Consumer Boxes I'm wondering how this can happen.

Even the best surge protection isn't an absolute guarantee, particularly for a very close strike.

 

What is the kA rating of your surge protectors? Do verify that the "failed" flag isn't showing.

 

You may want to add some of the small, round, surge devices to your LED lights, they are really cheap but do ensure that they're not near anything flammable.

As @Crossy said but to be more insistent. It is extremely unlikely that you will have a lightning protection system that will negate a near or close high energy strike.

 

It is certainly possible to do the work and spend the significant price to virtually stop damage from even a direct hit. However the work is significant and the costs run into the hundreds of thousands of dollars.

 

So the costs of a few replacements lamps and electrical items is insignificant related to the cost of protecting them.

 

Lightning strikes are not common enough for most people to want to spend that kind of money.

 

if you are in a high risk area, like some Japanese golf courses, then you take precautions, they have lightning protection bunkers on the courses. Or if you are outside then you need to understand how not to be a target (regrettably one of our villagers didn’t do that a year or two ago with a deadly result) 

 

So far my minimal precautions have resulted in zero damage to anything I own for over 70 years. Luck? Maybe. The results of being sensible? Possibly. If I get any damage then the amounts of money I haven’t spent over the years are more than enough to cover the costs
