Wave trap is a parallel tuned inductor - capacitor 'tank'
circuit made to be resonant at the desired communication
frequency.
It is the effort to utilize the same transmission line
between two substation for the purpose of communications.
At this communication frequencies the tank ckt provides
high impedance and does not allow to pass through them &
onto the substation bus & into transformers.

Answer / faizan

wave trap is used for filtering high frequency communication signal from power signal.
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/teleprotection 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 teleprotection signals and in addition, voice and data communication signals

wave trap is the instument which used to reduse the corona
loss in transmission line in power system and in this a
parellel tuned inductor -capacitor tank circuit made to be
resonant at the desire communication
it effort to utilise the same transmission between two
substations for the purpose of communication
