Hi
is it true that there is no way to get protection from a UPS in a bad whather conditions with lightnings?
though i don't have often lightnings in my area sometimes we get voltage spikes from the mains...so instead of spending money on a UPS (which i don't need...) or a multiple socket outlet with protections on it which usualy their prices are unreasonable high, i intent to build my own overvoltage protection using TVS and varistors.
i believe TVS are more effective than varistors but i got both of them.. the varistors are rated at 250V and the TVS at 128V and i'm going to use two TVS in series each one rated at 128V/1500W AC on 230V mains..
so i need some advices
