| Abstract: | When short circuit occurs in DC electric network high current happens, which may exceed the breaking capacity of the existing protection device. A new type of DC short circuit current limiter was designed using ultra fast circuit breaker technique. The working principle of this device was described. A prototype was developed and an experiment of high current breaking capacity conducted. From the results it is concluded that such current limiter can effectively restrain short circuit current from happening. |
