High-frequency wave trap for relay protection

A line trap, also known as wave trap, or high-frequency stopper, is a maintenance-free parallel resonant circuit, mounted inline on high-voltage (HV) AC transmission power lines to prevent the transmission of high frequency (40 kHz to 1000 kHz) carrier signals of power line. A line trap, also known as wave trap, or high-frequency stopper, is a maintenance...
