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. Oil breakers are typically used for voltages below 38 kV.
Substation circuit breakers detect abnormal current flow, then signal an automatic mechanism to open the circuit and stop electricity flow. This rapid response protects transformers, substations, and downstream equipment from power surges and electrical faults. The exact mechanism of their operation varies by breaker type.
The most common type is the air blast circuit breaker. These breakers use compressed air to extinguish an arc that has been created when the breaker is opened. Other types of circuit breakers include oil, vacuum, and solid state. There are different types of circuit breakers in substations.

There are three main types of medium voltage circuit breakers- air, oil, and SF6. Air circuit breakers use compressed air to extinguish the arc, while oil and SF6 circuit breakers use dielectric fluids to do the same. Oil circuit breakers have been around the longest, and were actually the first type of MV circuit breaker ever used.
A substation circuit breaker has three critical life stages: initial installation, maintenance and testing, and end-of-life. Following proper procedures at all of these stages will extend the life and enhance the efficacy of your circuit breakers.
