1. An arc fault detection system comprising:
a plurality of capacitive arc fault sensors electrically connected to a plurality of different segments of an electrical power distribution system, wherein each capacitive arc fault sensor is configured to output an arc fault signal based at least on detecting a high frequency current generated from capacitively coupling with an electrical arc; and
an arc fault detector electrically connected to the plurality of capacitive arc fault sensors, wherein the arc fault detector is configured to:
receive one or more arc fault signals from one or more capacitive arc fault sensors of the plurality of capacitive arc fault sensors; and
determine a location of an arc fault in the electrical power distribution system based at least on the one or more arc fault signals.
