ABSTRACT
This chapter describes transmission lines protection, distance relay as impedance, reactance, and mho relay will be discussed in this chapter. The fundamentals of differential protection systems used to protect transmission lines will also be discussed. Protection of parallel lines (Parallel operation) and Parametrizing non-directional relays using the SCADA system are discussed. Directional time overcurrent relays and High-speed distance protection using SCADA technology is explained in this chapter.
