I've told this story before, but, I'll do it again.
FPL needs to change something with their underground HV lines. They
"locate" the line at
the designated point, and then do what they call "punching" the line--
they use a special
Porta-Power attachment to punch thru the outer insulation and the two
"shields", as well
as what THEY call "semiconductor", all to insure that there's no live
connection to the
center lead, or any capacitive charge between the various layers. The
attachment to the
Porta-power is connected to a driven ground rod.
The Porta-power op assumes position, the FPL linemen hunker down behind
and... all goes well. Until the Porta-power guy utters those words we
all know, all too well:
"Oh, sh1t." Yep, that FPL HV line was really a telco 100 pair cable. The
"locate" was apparently
done well... it was just that the telco line was in the same trench,
above it. And the Porta Power
punched thru it quite nicely.
