Distance Relays are unique devices used to protect the transmission line from various faults but, series compensation exerts influence on distance relays. Distance Relays are very sensitive to the apparent impedance seen by the relay and its zone. This paper presents a study about the installation of series compensation in the midpoint of the transmission line, and its effects on the operation of a conventional three-stepped distance relaying schemes that are used for the protection of the same transmission line. It also proposes and validates a new algorithm based on integrated impedance methodology to detect, locate and classify different types of faults in a series compensated EHV/UHV transmission line. Integrated impedance is defined as the ratio of the sum of voltage phasors across two ends of the transmission line to the sum of current phasors through two ends of the same transmission line. It is used in the identification of faults inside the protected line section.
