[plug] Lightning risk

[Jim Householder]

Hi

Can anyone shed light on the risk of spikes due to lightning?

Our current setup is Mains --> surge board --> UPS --> computer-1.  #2 
has a more expensive surge board ($80,000 for damaged equipment type). 
I had the tv cable go through the fancy surge board but it caused very 
bad interference so it's bypassed now, but there is a VCR before the 
computer.

All mains powered equipment except the ADSL modem are surge protected, 
but only the computers and monitors are on the UPSs.

TIA
Jim
