The post arc phase is a critical part in the current interruption process of Vacuum Circuit Breakers (VCB). During this step, the dielectric strength of VCB has to be recovered. In order to improve the performance of VCB, investigation of Post Arc Current (PAC) in the presence of Transient Recovery Voltage (TRV) is presented in this paper. The equations of ion sheath length and PAC are solved together with network equations, which describe the TRV and PAC interrelation. In order to solve nonlinear ion sheath equations simultaneously with PAC and TRV equations, a Gauss-Seidel method is applied. The simulation results for PAC and TRV properly are in an acceptable accordance with the previous studies and available experimental records. The simulation results indicate that in the case of Short Circuit (SC) current interruption, there is no considerable influence between PAC and TRV. In the case of capacitive current interruption, TRV waveform in the first microseconds is highly influenced by the PAC. The results specifically demonstrate that the impact of physical parameters of VCB like diffusion time constant and initial PAC is much more significant than that of circuit parameters like capacitance of capacitor bank and equivalent network inductance.

This paper investigates the use of supercapacitor to mitigate the transient recovery voltage (TRV) in a simple power system. The TRV concept and the phenomena surround its occurrence such as re-ignition and restrike are represented. Also, the different waveshapes of TRV are evaluated. The effect of energizing different power system parameters, such as resistance and capacitance, resulting in TRV is evaluated. At first, the effect of energizing three different values of a damping resistance, one by one, is studied. Then, the influences of energizing of a capacitor, with three different values, on the tested system are illustrated. Finally, the effect of combining different values of the damping resistance and the capacitance are evaluated. The effect of using supercapacitor as TRV mitigation method is studied. Alternating transient program (ATP/EMTP) is used to simulate the test system and the proposed supercapacitor-based method. The simulation results ensure the validity of the proposed method.

“…According to [10], transient overvoltages are characterized by their short duration, potential oscillatory nature and typically strong damping. Practical investigations documented in several literature sources highlight that transient overvoltages pose a threat not only due to their magnitude but also because of their rate of rise [11][12][13]. Consequently, frequent overvoltages with smaller amplitudes but high rate of rise can be just as hazardous as overvoltages with larger amplitudes [14].…”

Electrical power systems are exposed to transient disturbances that change the voltage and current signals of the network, which can interrupt power and damage equipment. In high-frequency phenomena, it is essential to study the transient recovery voltage (TRV) to ensure the electrical insulation limits of circuit breakers are not violated, thus leading to a safe and reliable operation. Adequate models are crucial to achieving satisfactory results in the studies, according to the range of frequency of the transient being evaluated. This paper presents a comprehensive literature review of methods and models for studying electromagnetic transients, focusing on TRV requests imposed on circuit breakers, in addition to fault-clearing simulations on real system modeling. The analyses are fundamental both for the evaluation of the amplitude of the voltage signal and for its rate of rise. We also compare the reviewed models and techniques to provide a handy resource for researchers.
