The primary function of a fire department is to prevent and extinguish fires in its district. So if you don't have any fires, why do you need a fire department? Because with flammable fuels, electricity and people in the mix, fires are inevitable. So fire departments may train continuously, but they also train the public on how to prevent the fires, reducing the chances of a fire by educating the people in the fire equation. This is the key to prevention, and it's important because once a fire crew has to respond to a fire, it is too late—the damage has already been done. The question then becomes how to limit the damage. And the same thing applies in the power quality realm.
