Grounding Phone Line

[hockeyoligist2]

A friend asked me to check the ground on his phone line, ETC. this weekend, fed me some great BBQ for payment. He has lost the modem on his DTV receiver 2 times in the last year. He has had both the POCO and Bellsouth check things and they said everything is fine. It's a double-wide so everything is on a pole. Everything seems to be up to snuff. He said that he saw a flash at the phone plug right before the thunder. Would a separate ground rod for the phone help? Any suggestions?

A separate ground rod would probably make things worse, and would be a code violation as well.

I meant to say extra instead of separate ground rod. Connected to the other one also.

There's nice coverage in section 250.94. Single point grounding is all you can accomplish here.

PC cards now use opto isolation to help avoid damage from ESD events. I don't know of anything which will help with lightning strikes.

What about those radio shack wireless transmitters? You transmit within the house. They also allow you to put the unit wherever it's convenient. I can't imagine anything else with such a substantial amount of isolation. Perhaps there's something else I'm not familiar with. :-?

Is the phone system properly bonded to the electric system?

Check out the products using the following link. When these devices are properly bonded to the facility ground, it will reduce/mitigate effects from nearby lightning strikes that come down the telephone/cable lines.

Yes, it is.

Thanks for the link kc8dxx, I'll pass it along to my friend. Maybe he'll buy one.
