A New Method for the Measurement and Integration of Arc Durations in Electrical Contacts

A unique method for the continuous measurement of electric-arc duration is presented. By using the method, it is possible to know the distribution of arc durations at any instance of time and, at the same time, the integration of arc durations has become much more convenient and less time consuming than any other existing methods. It has also been found that the total integrated-arc durations bear a linear relationship with the number of operations on a log-log scale.
