Circuit breaker in substation in Ukraine

4 FAQs about [Circuit breaker in substation in Ukraine]

What type of Breaker is used in a substation?

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.
