2113 - Power Line Carriers

The objective of this videotape is to present a more detailed examination of power line carrier (PLC) systems. Earlier tapes looked at the protection schemes that employ PLC as the communication medium. This course focuses upon the PLC equipment itself. After study of this tape and the associated workbook, participants should be able to understand the following overall concepts and apply them to his day-to-day work activities. They will also be able to answer related test questions on these subjects: Principle of line traps, Inductors, series resonance with bus, LC line traps, parallel resonance, High Q and low Q traps, Two frequency traps, Wide band traps, Tuning line traps, Coupling capacitor grounding equipment, Carrier signal injection, Line tuning equipment, Impedance matching, Reflectivity, Standing wave test, Coaxial cable, Signal loss attenuation, Expression for loss in dB, Table: dB loss versus power ratio and voltage ratio, Examples of dB loss, dBm - examples, Loss between adjacent transmitter and receiver, Hybrid units, Transmitter basic components, Transmitter tests and adjustments, Receiver basic components, Receiver tests and adjustments, Line and coupling equipment tests, Special test equipment, Overall trip tests, Audio signals, frequency band, Modulation and demodulation, Upper and lower sidebands, SSB carrier equipment and features.

If you are taking this course for NERC credit, the following credits will be reported.
