Verification of arc discharge phenomenon and connection reliability

It is known that the arc discharge phenomenon occurs when the DC power supply is cut off. The arc discharge phenomenon has been verified for many of the literature etc. that exceeds 400 V dc / 10 A class voltage currents, but in our research it can lead to a big accident in micro arc regardless of voltage know. In this paper, we identify the cause of the accident caused by the arc discharge phenomenon generated by the low voltage direct current and show the countermeasure.
