That's the same sort of roller coaster ride I witnessed when we lost power during the storm last summer (we had at least three good brown-outs in about five seconds, pulling down the lights and cable box, before we lost power for good). A good surge protector will keep those dips and spikes from tearing things up, whether it's located at the equipment or at the main panel. Unplugging the vital stuff is even better protection, but impractical for storms that hit while at work or come on too quickly to react to.
