The purpose of this testing is to cause defects to occur during testing before placing a cable back in service. It forces weak cables to fail during testing.

That was in 2002, and to date, we haven't had any failures since we proof tested this cable.

Through this program, we get an opportunity to see for ourselves if this particular instrument makes sense and what it can do for us. It opens us up to other technologies that may prove beneficial.

A problem with the former method of testing is that it caused a treeing effect, which is a void in insulation. Charges that build up within these voids using the DC input method of testing would want to dissipate to ground, thus causing a breakdown in the cable's insulation, which would ultimately cause a failure.
