Development of deterioration diagnosis technique for bus Joint in Switchboards with temperature fluctuation

Abstract

We developed deterioration diagnosis technique for bus Joint in Switchboards. Increase of contact resistance by deterioration of a bus joint causes a temperature rise. However, it is difficult to really measure a temperature rise by a minute change of contact resistance. That is a method to detect a change of contact resistance of a bus joint as a temperature fluctuation. We expect that a serious accident such as a short circuit is prevented beforehand by this technique.
