two years our photography with a digital camera was often ruined
due to electrical surges

if a laser printer is turned on nearby, that causes a fluctuation
in the electrical current in that entire part of the building. That
in turn causes a dark band for that pixel row that the camera is
scanning during the period of the fluctuation. So the photograph

nearby refrigerator kicks on, that fluctuation in the current will
ruin any digital photography underway at that moment.
