Abstract :
Circuit breakers can fail to interrupt fault current when the power system has transient recovery voltage (TRV) characteristics that exceed the rating of circuit breaker. TRV is the voltage across the opening contacts of a fault interrupting circuit breaker immediately after the arc is extinguished. The actual shape of the transient is determined by the connected lumped and distributed inductive and capacitive parameters defined by the bus equipment connected. Most of researcher has worked on TRV but not so much work is done on rate of rise of recovery voltage (RRRV). In the present paper fast transient model of arrester is used to simulate and analyze the TRV and RRRV by using MATLAB-SIMULINK software. The results of this simulation show the benefit of fast transient model of arrester for this kind of study.
