A hypothesis regarding the feasibility of controlled electrical braking of a traction induction motor in this situation is analyzed. It has been shown that controlled electrical braking of a motor is possible in the case of significantly reducing the opening time of a high-speed circuit breaker's contacts compared to what actually occurs. However, this significantly increases the potential difference between the circuit breaker's contacts during opening. 09 25 2026 09 25 2026 335 30 https://creativecommons.org/licenses/by/4.0/ 10.37394/23201.2026.25.30 https://wseas.com/journals/articles.php?id=12096 RailGallery -Russia, Rostov region, Novocherkassk electric locomotive works, [Online]. https://railgallery.ru/photo/152084/?&lang=en(Accessed Date: August 16, 2025).
