Circuit Breakers’ Recovery Voltage Transients: Impact of Composite Loads and Power Network’s Configuration

  1. Mohamed Mostafa Saied

Abstract

The paper addresses the identification of the circuit breaker transient recovery voltage and its dependence on the loading conditions and the data of the power network, such as its rated power frequency and short-circuit level. A Laplace-domain approach is adopted and a closed-form expression for the recovery voltage is derived. A numerical inversion technique using Mathematica is implemented in order to get its time waveform. The proposed technique is applied to nine case studies.
