A discharge handling system includes: a power module; a power conversion device; and an arc discharge detection device, the arc discharge detection device including an arc discharge detector configured to detect occurrence of an arc discharge between the power module and the power conversion device, the arc discharge detection device monitoring the number of times of the arc discharge detected by the arc discharge detector and discharge time of the arc discharge every time a monitoring time elapses. The system includes a determination unit configured to determine necessity of maintenance within a predetermined period on condition that any of conditions (1) to (3) below is satisfied: (1) the number of times of the arc discharge in the monitoring time is from 1 to a number-of-times threshold inclusive; (2) each of the discharge time of the arc discharge in the monitoring time is equal to first determination time or less; and (3) total of the discharge time of the arc discharge in the monitoring time is equal to second determination time or less.
