The current scenario of electrical power systems, the Electrical Power System Quality 
(EPSQ) earns more notoriety. Among the EPSQ problems, Voltage Sags cause 
considerable financial losses and locating Voltage Sags sources is one of the biggest 
challenges for electric power utilities. In this context, the thesis that addresses a locator 
which identifies the source side of the Voltage Sag font is approached. However, as 
large electrical systems, in addition to meshed ones, are more complex, this work is 
responsible for evaluating the performance of such a locator, through the modeling of 
a real electrical system considering the insertion of Static Var Compensators. In the 
study, an RTDS® (Real Time Digital Simulator) platform will be used both in the 
modeling of the system, as in the implementation of the locator and in the evaluation 
of its performance.
