data communication signals. Line trap also is known as Wave. trap. What it does is trapping the high frequency. communication signals sent on the line from the remote. substation and diverting them to the telecom/teleportation. panel in the substation control room (through coupling. capacitor and LMU).
Step-down transmission substations are located at switching points in an electrical grid. They connect different parts of a grid and are a source for subtransmission lines or distribution lines. The step-down substation can change the transmission voltage to a subtransmission voltage, usually 69 kV. The subtransmission voltage lines can then serve as a source to distribution substations. Sometimes, power is tapped from the subtransmission line for use in an industrial facility along the way.
