Line Trap

Line Trap. A line trap also known as wave trap or highfrequency stopper is a maintenancefree parallel resonant circuit mounted inline on highvoltage (HV) AC transmission power lines to prevent the transmission of high frequency (40 kHz to 1000 kHz) carrier signals of power line communication to unwanted destinations.

Line traps are cylinderlike structures connected in series with HV transmission lines 132 kV 220 kV and 400 kV substation equipment and details The wave trap acts as a barrier or filter to prevent signal losses The inductive reactance of the line trap presents a high reactance to highfrequency signals but a low reactance to mains frequency.
