“…The implementation of this technique and its repeatability have been recently focused in many efforts. Reference [38]- [42] indicated that the measured resistance in this test is dependent on the injected DC current and opening velocity. The resistance decreases with an increase in the injectedcurrent and decrease of the velocity.…”

“…In recent years, several studies have been developed on this theme [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22]. However, these studies do not present an agreed methodology for measurement and analysis to define reference parameters to correlate the DRM results to the level of contact wear.…”

“…Therefore, for the complete consolidation of the DRM as contact degradation level technique, additional parameters beyond the area under the DRM curve should be addressed. Additional evaluating parameters were studied over the years, such as: the level of mass transferred by the contacts [15]; acoustic vibration [16]; average arcing and MC resistances (MCRs) [17, 18]; time difference between separation of the main and AC [19] and; maximum resistance over the entire curve [20].…”
