Abstract

The power relay can be easily controlled with high voltage and current through the contacts. For this reason, has become widely used range in a variety of applications. In this study, we measured the contact resistance between the bouncing phenomenon of contact due to the change of load. The results of the experiment, the contact resistance increases with the deterioration of the contact, it is possible to predict the life of the relay contacts through the contact resistance. And relay bounce duration time have occurred in 3.5 ms or less. In addition, it is possible to use the results to design an arc suppression circuit device.
