Substation circuit breakers vary based on their arc-quenching medium and voltage rating. Each type is suited to specific applications and offers advantages and limitations: Air (ACB): Use compressed air to extinguish arcs. These are typically used in low-voltage systems and offer simple construction but require regular inspection.
Whether in a utility-scale transmission yard or an industrial distribution hub, the breaker’s ability to detect faults and isolate problems makes it the backbone of substation protection systems. ✅ Automatically interrupts electrical current during faults to protect substation equipment like transformers and busbars.
In substations, circuit breakers serve as the first line of defence. When abnormal current is detected—due to equipment failure, insulation breakdown, or lightning—a breaker opens its contacts to interrupt the current flow. This rapid response prevents severe equipment damage, minimizes safety hazards, and ensures reliable power delivery.
