Lightning protection is installed in the complex: outside and inside the house. It would seem that the house is well protected by external lightning protection. Everything is correctly installed. The lightning receiver stands, as it should be on the skate of the roof, all the bends from it are fixed and connected to the ground. Lightning should be caught and neutralized in bad weather. But, it wasn’t there. If the zipper enters the house, of course, it will go into the ground, with good lightning, it will not have another way out. But, the discharge may not touch your house, but hit somewhere nearby. Power lines will transmit the excess of super -flow to your home electronics. The conductor in the house catches a high impulse, there is a jump in the tension, and you do not have more TV.
