Very good discussion going on lightning and surge protecion. I agree that the Delta SOV is a fairly crude device that provides very minimal protection against lightning or other high voltage transients. But its also relatively cheap - you get what you pay for... One very big drawback, as mentioned, is the lack of any fuses or lights to indicate whether its working, blown (other that a hole blown out the side), worn out, whatever. Jay: I recommended this company (Transtector) to my good friend and colleage Moby a few years back, after meeting & talking to them at their trade show booth. From my experience, they know as much as anyone about lightning and surge suppression. Moby bought and tested one of their units successfully at his mountain home, as you said. The CB & DCB series are their transient suppressors for 24 and 48 VDC power distribution systems.

They are expensive but worth it. I think the Deltas seem OK for low power lightning at some distance but don't seem to work at hi power/close ranges. But then I'm fortunate, as I don't live in a lightning area. jay peltz power Allan Sindelar wrote: > ----- Original Message ----- > From: > > > I did get the impression the factory was not sure what is going on when we > > talked to them.
