Does a line trap act as a filter to prevent incoming communication signals from passing through a substation?

Explanation:
Line traps are tuned RF filters placed at the boundary of a substation to separate high-frequency communication signals from the normal 60 Hz power flow. They are designed to pass the power frequency while presenting high impedance at the PLC (high-frequency) signals, effectively trapping that RF energy and preventing it from propagating into or through the substation. This makes the statement true: a line trap acts as a filter to keep incoming communication signals from passing through a substation. They do not amplify signals or convert them to DC.
