Power Line Carrier
Although fiber optic and microwave-based digital
communication systems have augmented or replaced many traditional
PLC-based
communication systems, PLC (Power-line Carrier) continues to be one of
the most
cost-effective solutions to cover the operational needs of a wide-area
power
system.
PLC systems typically represent a large long-term investment
on the part of many utility companies, and it is seldom possible to
replace
entire PLC systems all at once. In
other cases, PLC channels are still useful as backup channels or for
simple
low-cost installations that do not require the installation of new
digital
lines.
For
this reason, CC&E Engineers continue to specialize
in the design and implementation of PLC-based communication systems.
