Milk thistle is now found throughout the eastern United States, California, and South America. The plant grows up to 2 meters high and has large, bright purple flowers.
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).
Potential transformers and coupling capacitor voltage transformers (CCVTâs) have been used successfully. for providing voltage to the inputs of meters and relays since the 1960âs. At voltage levels above 138kV. economics dictate that CCVTâs be used to provide secondary voltages to relays. As weâll see later.
