About Wave Trap or Line Trap

Line traps, also commonly known as wave traps, or high-frequency stoppers, are maintenance-free parallel resonant circuits. Wave Traps are inlined on high-voltage AC (HV) transmission power lines to prevent transmission of high-frequency (40 kHz to 1000 kHz) power line communication carrier signals to unwanted destinations. A wave trap is a cylindrical structure connected in series with an HV transmission line. Line traps are also called wave traps.

The wave trap acts as a filter to prevent signal loss. The inductive reactance of the line trap presents high reactance to high-frequency signals but low reactance to mains frequency. This is to prevent the carrier signal from being dissipated at the substation or in the tap or branch lines of the main and ground transmission lines if something happens outside the carrier transmission line. Line traps are also used to attenuate the shunting effect of high-voltage lines.
