1. An arc detection system comprising:
a first obtainment unit configured to obtain a measurement result of current flowing in a power line to which power is supplied from a power supply or a measurement result of voltage in the power line;
a second obtainment unit configured to obtain operation information about operation of a device connected to the power line; and
a determination unit configured to determine whether or not an arc fault has occurred in the power line based on the measurement result obtained by the first obtainment unit and the operation information obtained by the second obtainment unit,
wherein the operation information indicates a communication status with the device, and
when the determination unit determines that an arc has occurred based on the measurement result obtained by the first obtainment unit and there is a difference in the communication status indicated in the operation information before and after the determination, the determination unit is configured to determine that the arc fault has not occurred.
