Arc fault detection in an electrical power distribution system

An arc fault detection method for an electrical power distribution system, the method comprising:

• receiving one or more arc fault signals from one or more capacitive arc fault sensors of a plurality of capacitive arc fault sensors electrically connected to a plurality of different segments of the electrical power distribution system, wherein each capacitive arc fault sensor of the plurality of capacitive arc fault sensors 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
• determining a location of an arc fault in the electrical power distribution system based at least on the one or more arc fault signals.

A storage subsystem holding instructions executable by a logic subsystem to:

• receive one or more arc fault signals from one or more capacitive arc fault sensors of 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 of the plurality of capacitive arc fault sensors 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
• determine a location of an arc fault in the electrical power distribution system based at least on the one or more arc fault signals.
