Abstract	Transmission lines play an important role in power system as far as reliability is concerned. The transmission line must have a good maintenance and switching plan to get the most of its reliability. However, no matter how good the system, the failure rate of the transmission line cannot be suppressed to zero and when it does fail, it causes a wide-area outage which impacts various customers. In MEA's distribution system, 2 transmission lines are provided to link a substation to 2 different terminal sources. However, in a downtown area, routing of the transmission line is very difficult and costly to provide two terminal-station transmission lines to each substation. Thus some substations have to receive electric power from a nearby substation instead. Significantly, all of the nearby substations called inline substations have only one source due to have to pass through electric power to other substations. Their reliability is low, since they cannot perform substation line transfer functions (CTO/LTO). This paper presents the implementation techniques of inter-substation line transfer function (ILTF) using SCADA, IEC61850 GOOSE and PLCs which resulted in a huge outage time reduction.
