The development of renewable sources of electrical energy represents the main goal of the most countries. This energy has to
be transmitted for a long distance for the utilization in populated areas. The need of high-voltage direct current circuit breakers
represents the key of the development of high-voltage direct current transmission systems. High and extra high-voltage six
sulfur hexafluoride circuit breakers need more than one interrupter to be stable during arc extinguishes, so it can be used in
high-voltage systems as cascaded interrupters. In this article, the multi-break high-voltage direct current HVDC gaseous circuit
breaker characteristic is investigated by employing Mayr and Cassie arc models. The influences of the models parameters on
the arc interruption time are studied using MATLAB/Simulink program. It is concluded that the simulated results by employing
black box arc models achieve a success in multi-break HVDC gaseous circuit breakers simulation. Employing BBAMs black
box arc models has proved more flexibility to study the effect of different controlled and uncontrolled parameters on the
multi-break high-voltage direct current gaseous circuit breaker HVDCGCB arcing time. That has proved more flexibility to
study the effect of different controlled and uncontrolled parameters on the arcing time. The main contributions of this article
in points can be summarized as employing black box arc models achieves a success in multi-break HVDC gaseous circuit
breakers simulation, investigation of the influence of commutation parameters on the cascaded HVDC gaseous circuit breaker
interrupter performance, the controlled and uncontrolled parameters affecting the arcing time of HVDCGCB has been studied,
the impact of the fault resistance value on arcing time and the damping resistance influence on the transient recovery voltage
are investigated, and additionally, the initial transient interruption and the Metal Oxide Varistor voltages are analyzed. From
the investigated forty cases done to check the Mayr’s model validity in the HVDC CD simulation, it is found that the values
of P and τ which give acceptable outputs are at τ 10−6 s, and P in range of 107 W to 1011 W. The output of the case τ
10−6 s, P 1010 W, which is introduced in the paper has proved that when τ reached to 10−7 s the MOV current rises and
drops and thereafter rises and gradually decreases. This may leads to CB failure Com parameters influence on the interrupter
performance are investigated and proved good simulation of the gaseous circuit breaker interrupter.
