Explanation:Types of applications for Air Blast Circuit Breakers:- Arc furnace duty: Air Blast Circuit breakers are commonly used in applications such as arc furnace duty due to their ability to quickly extinguish the arc and interrupt the current flow. The high-speed blast of air helps in cooling and de-ionizing the arc, making it an effective choice for this application.
- Traction system: Another application where Air Blast Circuit breakers are employed is in traction systems. These systems require reliable and efficient circuit breakers to protect the electrical equipment from overcurrent and short circuits. The Air Blast Circuit breaker's ability to quickly extinguish the arc makes it suitable for this application as well.
Therefore, the correct answer is option
C -
i and ii both. These circuit breakers are utilized in both arc furnace duty and traction systems due to their effectiveness in interrupting the current flow and protecting the electrical equipment.
