MagSafe 2 45w Not working after high voltage fault

My charger is not working after a high voltage fault occur in my locality. At the time of fault my charge was at ideal position I.e. was not using at that moment for charging, my charger was plugged in board and switch was on but was not using it to charge, after electricity retained back my charger was not working. In fact almost all charger of my home gone. So what are possible damaged comments in my MagSafe 2 45w charger
