In repair we find that most of the time the outer contacts of the PV receptacles are the first to fail. Adapter cards plug into interface connectors which are designed for many mating cycles. PV receptacle life can be shortened from bent pins on adapter cards that are damaging the internal connections of the PV receptacle or failure to properly use a cover-plate during testing that causes the adapter to rock back and forth inside of the PV receptacle. Some tips to prolong the life of your receptacles:

Check adapter cards for bent pins.
Straighten bent pins carefully with smooth long nosed pliers.
Use cover-plates during testing.
Align adapter cards with receptacles before inserting adapter into receptacles.
Carefully remove adapter cards.
Replace defective or damaged adapter cards.

Have you ever been frustrated trying to find the actual cause of a high voltage failure in a cable assembly? The type of high voltage failure can give clues to the type of defect occurring. Pinched and narrowed insulation causes dielectric failures while contamination and humidity are most likely to cause insulation resistance failures. To better understand these types of failures and to more easily identify their root causes see our second video on High Voltage testing.

What mental images do you have about testing cables with high voltages? What images do people on the production floor have when they get failures? If this is a mystery, a simple water metaphor may help you understand hipot testing a little better. We find that it helps many people understand specifically how high voltage tests identify insulation defects. It may help you better understand high voltage testing using Cirris' 1000H+, 1100H+, Touch 1 and CH+ testers.
