Tensão de restabelecimento transitória em disjuntores de alta tensão.

Abstract

The purpose of this research was to analyze the transient recovery voltages and the relevant aspects that should be considered in the specification of circuit breakers. This work analyze the behavior of overcoming power system circuit breakers according to the type of fault the system is subjected to, the system voltage level and the fault distance with respect to the circuit breaker terminals. For the characterization and implementation of the eletrical system studied, PS Simul (Power System Simulator) software was used. The results of the simulations are presented oscillograms of electrical quantities and follow as validation of the presented theory.
