How to represent wave traps in electrical single line diagram?

Question

what is the basic principle of using wave traps in transmission line?

Answer 1

Wave Traps are used in Power Line  communication.As you can imagine, it takes some unusual engineering to couple a radio signal onto an antenna carrying 500,000 volts. . One of the devices employed in Powerline Carrier is the Line Trap, sometimes called a Wave Trap. A wave  trap is a parallel resonant circuit installed on the powerline at the local substation. It is tuned to resonate at a specific frequency or frequencies. These frequencies are equivalent to the TxRx frequencies of the local powerline carrier transceiver. Properly tuned, the line trap shows its highest magnitude of impedance, � Z � , at these carrier frequencies while permitting the 60 Hz power frequency to pass.

generally represented as  inductor  with a capacitor in Parallel .
