operation is difficult and can lead to operation errors. The degree of reliability and flexibility of this arrangement is not very high, but due to its relatively low cost, this arrangement is widely used in Brazil. 13 A look at development Application analysis of disconnecting circuit breaker in different substation arrangements
This type of breaker uses compressed air to extinguish the arc that is created when the contacts open. Air blast breakers are generally used for voltages above 38 kV. Another type of circuit breaker that can be used in a substation is the oil circuit breaker. This type of breaker uses oil to quench the arc created when the contacts open.
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.
Circuit breakers perform two fundamental roles in substations: (1) interrupt high fault currents safely to protect equipment and limit system disturbance, and (2) provide a means of making and routing power during normal operation (switching, sectionalizing).
