In my previous posts i already explained how Power Line Communication is carried out using existing Power Lines / Transmission Lines. While discussing it was also mentioned that PLC System comprises of Outdoor Equipment in addition with other components.
Following is the List of equipment covered under Outdoor Equipment.

Capacitive Voltage Transformer serves TWO purposes. Used for Metering and provides easy path to High frequency Signal.
Line Matching Unit, like CVT also serve multi purposes. It is used for Impedeance Matching between Transmission Line and High frequency Coaxial Cable and more importantly provides protection against High Voltage Hazards
