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.

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.
