- Wave trap is a parallel tuned inductor - capacitor tank circuit made to be resonant at desired communication frequency . It reduces corona losses in transmission lines in power system.
- Wave trap is installed in the substation for trapping the high frequency communication signal sent on the line from remote substation and diverting them to the telecom panel in substation control room. These high frequency signal should not be coming on the buses as these may damage the equipments .
- A wave trap is a device that allow only a particular frequency to pass through it that it filters the signals coming on to it . So a wave trap is connected between buses and the transmission line which allow only 50 Hz signal to pass through it.
- This is relevant in power carrier communication (PLCC) system for communication among various substation without dependence on telecom company network . The signals are primarily teleportation signal and in addition , voice and data communication signal.
