No surge protector will help if lightning strikes between the power-pole transformer and the power lines running to your house.
Surge protectors work for voltage anomalies, but WILL NOT PROTECT EQUIPMENT FROM A LIGHNING STRIKE!!! Unplug [don't just throw the circuit breaker] your gear if there is electrical storm activity in your area!
