I know you don't want to hear this, but if that's the case, they should be 
immediately decommissioned as a safety hazard.

This business of 'Ethernet surge protectors' isn't viable - if equipment on one 
end of a data connection is shorting out equipment on the other end of a data 
connection, the underlying electrical problems *must* be solved.

You can run copper between buildings in underground or aboveground conduits, if 
they're properly shielded - but it isn't a good idea due to RFI, etc.
