Power Line Carrier Subcommittee (C0)

Scope

  1. Studying and reviewing engineering, operational, and testing aspects of specific power line carrier applications as they apply to the Electric Power System.
  2. Developing and maintaining related standards, recommended practices and guides for such aspects.
  3. Coordinating with other technical committees, groups, societies and associations as required.
  4. Preparing and arranging for publication technical reports related to the Subcommittee’s scope.

C1 WG: IEEE P643 – IEEE Guide for Power Line Carrier Applications
Chair: Tony Bell Vice-Chair: Dave McGuire
Scope: Material on power line carrier channel characteristics is presented along with discussions on intra-bundle conductor systems and insulated shield wire systems. Procedures are provided for the calculation of channel performance. Data for the calculations is drawn from various sections of the guide. The coupling components considered are line traps, coupling capacitors, line tuners, coaxial cables, hybrids, and filters. Frequency selection practices are also discussed. Detailed equipment design information is avoided as this is primarily the concern of equipment manufacturers. Information related to the expanding usage of carriers on distribution lines below 69 kV is not covered.

Status: Active

C2 WG: IEEE PC93.4 Standard for Power Line Carrier Line-Tuning Equipment (30 kHz to 500 kHz) Associated with Power Transmission Lines
Chair: Dave McGuire Vice-Chair: David Williams
Scope: This standard applies to 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. 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 devices that facilitate the operation and maintenance of the line-tuning components. This standard develops technical definitions, performance ratings, testing methods, and manufacturing requirements for the included line-tuning equipment.

IEEE-C93.3  Standard Requirements for Power Line Carrier Line Traps
Chair: Bruce Pickett    Vice-Chair: Roger Ray
Scope: This standard applies to a line trap inserted into a power line to provide a high impedance at power-line-carrier frequencies (30-500 kHz). The purpose is to isolate the carrier signal from system impedance changes due to faults or switching behind the point of insertion, and guide the signal in the proper direction. The standard covers line traps in which the main coil is designed as a single phase, air-cooled inductor of the dry type.

IEEE-C93.5  Standard for Requirements for Power Line Carrier Transmitter/Receiver Equipment used to Transfer Discrete Teleprotection Signals
Chair: Craig Palmer    Vice-Chair: Tony Bell
Scope: This standard describes requirements for power line carrier (PLC) transmitter/receiver equipment used to transfer discrete teleprotection signals at power-line-carrier frequencies (30-500 kHz). Test requirements and conditions for determining performance, as well as manufacturing requirements, are defined. This standard does not include broadband or single sideband (SSB) power line carrier equipment used for data transmission, nor does it include terminal equipment used on distribution circuits for the purpose of load management or automation.
