This paper dicusses the redundancy in coupling power line carrier channels to the power line. First, is a basic discussion of coupling schemes and the important factor of efficiency. Second, is the presentation of various coupling methods. Last is a discussion on which schemes provide the best overall system redundancy as related to primary, secondary protection and the application of the carrier system and the common mode device failure that could render the carrier problematic or ineffective.
