what is Wave Trap? And its Function ? Detail? Where it is Used?
Answer Posted / shailendra
Line trap also is known as Wave trap. What it does is
trapping the high frequency communication signals sent on
the line from the remote substation and diverting them to
the telecom/teleportation panel in the substation control
room (through coupling capacitor and LMU).
This is relevant in Power Line Carrier Communication (PLCC)
systems for communication among various substations without
dependence on the telecom company network. The signals are
primarily teleportation signals and in addition, voice and
data communication signals. Line trap also is known as Wave
trap. What it does is trapping the high frequency
communication signals sent on the line from the remote
substation and diverting them to the telecom/teleportation

The Line trap offers high impedance to the high frequency
communication signals thus obstructs the flow of these
signals in to the substation busbars. If there were not to
be there, then signal loss is more and communication will
be ineffective/probably impossible.
