This paper presents the measured impedance at the relaying point in the presence of a series
connected Flexible Alternating Current Transmission System (FACTS) device, i.e. Static
Synchronous Series Compensator (SSSC). The presence of SSSC on a transmission line has
a great influence on the tripping characteristic of distance relays. The distance relay tripping
characteristic itself depends on power system structural and pre-fault operational conditions
and, especially, the ground fault resistance. In the presence of SSSC, its controlling parameters,
as well as the connection point of the instrument transformers of distance relay affect the
tripping characteristic. Here, measured impedance at the relaying point is calculated, due to
the concerned parameters.
