Even if an abnormality occurs, the surroundings will not be affected. Overcurrent Check Experiment

Overcurrent check experiment is, as the name suggests, an experiment with a strong electric current. This is to check the condition of the cables and otter things when a current over the normal amount is applied. This was added as further testing by the request of NASA.

This is because we needed to know two things should an abnormality cause overcurrent in the ISS; “if the cables will burn or be damaged” and “if there will be a bad influence on the environment inside the ISS.”

In this experiment we applied an electrical current of 4.2V to the cables. The temperature rose, but the cables did not burn or break and passed the test. We successfully cleared the test by NASA.
