Power-line carrier (PLC) line-tuning equipment connected between the coupling capacitors and PLC transmitter/receiver terminals operating in the frequency range of 30 kHz to 500 kHz over power transmission lines and cables or to similar line-tuning equipment in a carrier bypass are addressed in this standard. PLC line-tuning equipment includes assemblies and components: tuning inductor, impedance matching transformer, balancing transformer, tuning capacitor, inductance-capacitance (LC) tuning unit, hybrid, filter, protective unit, interconnecting cables, and enclosure. This standard includes the protective devices that facilitate the safe operation and maintenance of the line-tuning components under normal and usual operating conditions. This standard will develop technical definitions, performance ratings, testing methods, and manufacturing requirements for the included line-tuning equipment.

IEEE Guide for Power-Line Carrier Applications
Revision of IEEE Std 643-1980 The purpose of this guide is to provide application information to users of carrier equipment as applied on power transmission lines. Since the major applications of the power-line carrier (PLC) is for protective relaying, special consideration for these applications has been included. Information related to the expanding usage of carriers on distribution lines below 69 kV is not specifically covered. Detailed equipment design information is avoided as this is primarily the concern of equipment manufacturers.
