DETERMINATION APPARATUS, DETERMINATION METHOD, AND PROGRAM
A determination apparatus includes: a cutoff unit configured to cut off and connect a power line connecting a DC power supply and a load device; a measurement unit configured to measure a current value flowing through the power line; and a determination unit configured to perform an operation of connecting and cutting off the power line a plurality of times using the cutoff unit and determine whether a predetermined event has occurred based on a change in the current value measured by the measurement unit in the plurality of times of operations.
1 . A determination apparatus comprising:
a memory; and
a processor coupled to the memory and configured to:
cut off and connect a power line connecting a DC power supply and a load device;
measure a current value flowing through the power line; and
perform an operation of connecting and cutting off the power line a plurality of times-using the cutoff unit and determine whether a predetermined event has occurred based on a change in the current value measured in the plurality of times of operations.
2 . The determination apparatus according to claim 1 , wherein
the processor is configured to determine that an inrush current has occurred when the current value decreases in the plurality of times of operations, and to determine that a short-circuit current has occurred when the current value does not decrease in the plurality of times of operations.
3 . The determination apparatus according to claim 1 , wherein
the processor is configured to disable an overcurrent cutoff function when the processor determines that an inrush current has occurred based on the change in the current value.
4 . A determination method executed by a computer in a system including: a memory; and a processor coupled to the memory and configured to: cut off and connect a power line connecting a DC power supply and a load device, and measure a current value flowing through the power line, the determination method comprising:
performing an operation of connecting and cutting off the power line a plurality of times and determining whether a predetermined event has occurred based on a change in the current value measured in the plurality of times of operations.
5 . A non-transitory computer-readable recording medium storing a program causing a computer to perform the method of claim 4 .
