摘要

瞬时跳闸可以通过减少清除故障的时间来减少600伏和5千伏控制电路的电弧闪光能量水平。瞬时通常不使用，因为与大型电机启动器的协调可能会丢失。哪个更重要?数字多功能继电器可以使用瞬时跳闸函数的傅立叶变换算法来改善与起动器中的限流熔断器的协调

Use of Instantaneous Trip Functions and Current Limiting Fuses to Reduce Arc Flash Energy

The instantaneous trip can be used to reduce arc flash energy levels at 600 volt and 5 kV MCCs by minimizing the time to clear faults. The instantaneous is often not used since coordination with large motor starters can be lost. Which is more important? A digital multifunction relay may be able to use the Fourier transform algorithms for the instantaneous trip function to improve coordination with current limiting fuses in starters
