When a short circuit occurs in the power system, a large short-circuit current will be generated. If not limited, it is very difficult to maintain the dynamic stability and thermal stability of electrical equipment. Therefore, in order to meet the requirements of breaking capacity of some circuit breakers, reactors are often connected in series at the outgoing circuit breaker to increase the short-circuit impedance and limit the short-circuit current. Due to the use of reactor, the voltage drop on the reactor is large in case of short circuit, so it also plays a role in maintaining the bus voltage level. It makes the voltage fluctuation on the bus less and ensures the operation stability of user electrical equipment on the non fault line. This is how the reactor works.
