摘要： PROBLEM TO BE SOLVED: To provide an arc flash detection system that reliably detects arc flash events and mitigates nuisance trips of circuit protection devices.SOLUTION: A power circuit protection system 100 includes a current sensor 106 to measure a first current level through a conductor of a circuit 104, a voltage sensor 110 to measure a first voltage level across a plurality of conductors of the circuit 104, and a controller 116 communicatively coupled to the current sensor 106 and to the voltage sensor 110. The controller 116 receives a first signal from the current sensor 106, in which the first signal is representative of the first current level, and receives a second signal from the voltage sensor 110, in which the second signal is representative of the first voltage level. Based on the first signal and the second signal, the controller 116 determines whether to activate a first circuit protection device 112 or a second circuit protection device 114.
