Abstract: A load test apparatus includes: a first resistance unit that has a plurality of first resistors and a first holding part holding the plurality of first resistors; and a first cooling part that includes a cooling device sending cooling air to the plurality of first resistors; a control part that includes a power source terminal part connected to a power source to be tested and an operation part; and a relay part that includes a switching device connected to the power source terminal part and the first resistance unit. The cooling device in the first cooling part faces one first opening in the first holding part. The first cooling part and the first resistance unit are arranged in a third direction (z direction) orthogonal to a first direction (x direction) and a second direction (y direction), and a first load test part.

Abstract: To provide a detection system to identify a damage or a damaged part. A detection system includes a power generator, a power storage unit that receives first power supply from the power generator via cables, and detectors that perform at least one of outputting information and transmitting the information when it becomes in a state in which a weak current does not flow by a predetermined amount during a period when the weak current is passed to the power generator via at least part of the cables under a situation where the first power supply is not provided.

Abstract: Provided is a power generation system including a wave power generator that can be configured in a simple manner. The power generation system 1 includes: a power generation unit including a wave power generator 11; a power storage unit 40 accumulating electric power obtained by the power generation unit; a production unit 51 producing at least one of hydrogen and an organic hydride based on the electric power obtained by the power storage unit; and a tank 53 located below compared to the wave power generator 11 and storing at least one of the hydrogen and the organic hydride obtained by the production unit 51.

Abstract: A load testing device or the like having a structure in which cooling air does not leak, is provided. A load testing device includes: a resistance unit having a resistor and a resistor holding frame holding the resistor; a cooling unit having a cooling fan; and an insulating frame disposed between the resistance unit and the cooling unit. The insulating frame is coupled with the resistance unit. The insulating frame is coupled with the cooling unit. The insulating frame covers a side surface of a flow path of cooling air from the cooling unit to the resistance unit between the cooling unit and the resistance unit.

Abstract: A load testing device includes a connection unit to which a power source being tested is connected, a hydrogen generating unit that performs electrolysis based on power supplied from the power source being tested to generate hydrogen, two or more supply units to which hydrogen obtained in the hydrogen generating unit passes and to which a portable tank is removably attached, and an operational unit that has a load amount adjustment switch and a display unit. The load amount of the hydrogen generating unit is switched depending on an operational state of the load amount adjustment switch. The display unit displays at least one of an attachment status of the portable tank and a filling status of hydrogen in the two or more supply units.
