Power Transmission Lines Cooling in Under Ground Cables and Overhead Lines
The transmission line cooling system is a necessary technique to cool down the transmission network to improve the power transmission efficiency. This real time transmission line cooling system that replaces existing aluminum core into copper core. Temperature sensor is used to monitor copper coil’s energy and monitors the parameters of transmission line load current and voltage. External coolant oil / water is used to maintain the constant temperature at transmission line. The oil-filled cable is used widely with the higher voltage ratings, and it was known that the central duct is adapted for internal cooling. The development of internally cooled cables, based on the self-contained oil-filled cable together with a full range of accessories and ancillary equipment is proposed.
