“…This concept takes into account the non-simultaneity of the interruption of the arc in the three phases. Furthermore, the most severe oscillatory or exponential recovery voltages tend to occur across the first pole to open of a circuit breaker interrupting a three-phase ungrounded symmetrical fault at its terminal when the system voltage is maximum [131].…”

“…To establish reference parameters for TRV values, envelope curves have been developed to indicate the capability of the investigated circuit breaker. These envelope curves are specified in standards such as [131][132][133]. The standard [133] standard [118] defines the TRV envelope, which can be represented by two or four parameter curves.…”

“…On the other hand, according to the standard [132], TRV behavior varies in systems with voltage equal to or greater than 100 kV. Initially, there is a high RRRV, and, later, this rate is reduced [131].…”

“…The oscillatory or exponential recovery voltages typically occur when the first pole of a circuit breaker opens during the interruption of a three-phase symmetrical fault without grounding at its terminals, while the system voltage is at its maximum [131]. In the case of a three-phase ungrounded fault, the first pole factor is denoted by a constant of 1.3 for effectively grounded systems.…”

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.
