is this what you need? put in parallel as much as your budget allows it
it is a very complicated matter , in your case, you lost power and then the power was back. Think about it as a big power supply loaded onto very long cables (transmission lines) . You trip it, it goes into emergency and disconnect itself. once issue is removed, it is back. Now transmission line is inductive plus capacitive load. There are 2 laws to follow. You cant stop current trough inductive load, if you break the line, it will manifest itself into a huge spark. Capacity of the load is what charge it during initial process. Second one is capacitor absorbs the current up to a certain point, then it is charged.
Any drama with your grid can be broken down like that:
-voltage is gone, than come back with huge spike that is determined by transmission line characteristic
-power of this SPIKE is impossible to calculate.
these are all my ideas just to explain the nature of power in grid line.
Best idea is get INDUSTRIAL UPS (cost lots of money), or DIESEL generator to avoid dealing with cowboys , or
install surge suppressors as much as you can afford and hope for the best. Some of them have reaction time PICO ( -9) seconds and that is very impressive.... but in real life they are all designed to burn themselves out while protecting you stuff. That is the nature of the ultra fast diode or super fast transistor. It will protect your machine while burning itself.
