A methodology to determine Transient Recovery Voltage in short-line fault

Abstract

This paper presents a methodology to determine the appropriate parameters to establish the capability of Transient Recovery Voltage (TRV) of a 145kV circuit breaker. The methodology involves the combination of a simulation procedure in the Electromagnetic Transients Program (ATP) and an analytical technique based on the IEEE C37.06 and IEC 62271-100 standards to evaluate the effect of the source side voltage and line side voltage on the TRV in a short-line fault (SLF). The results obtained on TRV of the circuit breaker capability by simulation and analytical calculation, acording to the IEEE and IEC standards, are compared using the Matlab program.
