This chapter describes using optical waveguide for communication between two relays on the opposite ends of the power systems transmission line (or transmission line). Transmission lines are a very important part of the power system. Because of that, relay protection must be fast and safe. Longitudinal differential protection satisfies these requirements. Pilot wire differential relays are commonly used for the protection of short lines. The existence of the pilot wires is a disadvantage. This protection is limited to lines of a few tens of kilometers. However, if optical protection ground wires (OPGWs) are used, instead of pilot wires, the length of the line ceases to be a limiting factor. The following sections tell more about constructions, assembly and utilization of the optical waveguides in differential protection. Also, the newest algorithms of this protection are listed.

“…Sensitivity, selectivity and reliability of the conventional current differential protection are affected and limited by the presence of distributed capacitances along transmission lines, especially in high-voltage long transmission lines [5,6]. These problems are resolved by a newer version of differential protection based on the active and reactive powers measured at the both line ends [7][8][9][10][11]. Power differential protection is a pilot protection scheme introduced to prevent the disadvantages of current differential protection in the presence of capacitive charging current.…”

In this study, a novel scheme is proposed for pilot protection of transmission line based on the fault component integrated power (FCIP). An appropriate definition is proposed for FCIP. The proposed scheme is able to quickly discriminate the normal condition, internal fault and external fault situations, even in severe operating and emergency conditions. This FCIP-based scheme is not affected by the line charging capacitive and, therefore it does not need to be compensated for the capacitive current. Hence, this novel pilot protection scheme, based on FCIP, can be used for long distance high-voltage transmission lines. The faulty phase/phases can also be detected by the proposed scheme. Moreover, compared with a newlyintroduced protective scheme which is based on the fault component integrated impedance, the proposed FCIP-based scheme has faster operation speed. The efficiency of the proposed protective scheme is evaluated and approved over extensive simulation studies.
