  • What is HVDC Circuit Breaker? - Problem of HVDC Circuit

    The HVDC circuit breaker is a switching device that interrupts the flow of abnormal direct current in the circuit. When the fault occurs in the system the mechanical contacts of the circuit breaker are pulled apart and thus the circuit is open. But in HVDC circuit breaker the circuit breaking is difficult as compared to AC circuit breaker because the direct current is unidirectional and there

  • High-voltage direct current - Wikipedia

    High-voltage DC circuit breaker. HVDC circuit breakers are difficult to build because of arcing: under AC the voltage inverts, and in doing so crosses zero volts, dozens of times a second. An AC arc will self-extinguish at one of these zero-crossing points, because there cannot be an arc where there is no potential difference.
