| "Power Outage"
I have seen electronic damage that seemed to occur during a power outage. Acutally it may have occurred at about the same time as the power outage. You mention 'storms'. When lightning strikes the power system, it is designed to automatically trip off momentarily and then restore power. I believe it is more likely that energy from the same nearby lightning strike that caused the interruption also came into the shop. And it is also likely that the energy (surge) did damage due to improper grounding scheme. Always beware of multiple isolated ground rods in a building; it is an invitation to lightning related damage. |
