The connector differs from conventional twist-on connectors in that it is pre-filled with a corrosion inhibitor compound containing suspended particulates. Burnout occurring among these splices led to removal and replacement of all of the new connectors. In this study, the connectors removed from 102 apartments were inspected for signs of overheating and for indications of abnormal conditions that might cause the failed connectors included samples that were applied to rated wire combinations and showed no sign of abnormal installation or application conditions. Tests of the aluminum conductors from the apartments reveal no abnormalities that could account for the poor performance of the new connector. The inhibitor compound inside the connector was determined to be of limited effectiveness in improving the wire-to-wire contact through the high resistance film on the aluminum wire surface. On the basis of the field failures in combination with previously reported laboratory studies it is concluded that the connector is not suitable for permanent use with aluminum wire residential wiring systems.","PeriodicalId":299141,"journal":{"name":"Electrical Contacts - 1999.

The focal point of this macro-wear study is the increase in the contact resistance when the pure-tin layer is removed and the rider slides on the hard and uneven intermetallic compound, which is referred to as Stage II. Stage II has been divided into two \"sub-stages\", referred to as Stage IIa and Stage IIb, with the transition point between the two defined by a sharp rise in the magnitude of the voltage drop. The transition between Stages IIa and IIb ranged between 70-130 mV, independent of current load. The upper and lower ends of this range correspond to the softening and fusion voltages of tin respectively. The sliding speed has a significant effect on the deterioration during Stage IIa, while the current load does not significantly influence the deterioration as long as the electrically-induced heat is low. In this study an outline of an oxidation model is proposed for describing the deterioration during Stage IIa, and to determine an oxidation constant. Furthermore, the length of duration of Stage IIa can be derived and expressed simply as the inverted value of the oxidation constant.","PeriodicalId":299141,"journal":{"name":"Electrical Contacts - 1999.

This apparatus which includes a piezotranslator, enables controlled bouncing to be studied at make under mechanical conditions similar to those encountered in automotive relays. Material transfer and welding tendency of silver, silver alloys and silver metal oxide contact materials have been studied under inductive, resistive and lamp loads at 14 V DC and 10-70 A. With all loads, anode to cathode material transfer has been observed, AgCdO, Ag and AgNi under lamp and resistive loads show the highest material transfer, as opposed to non doped and doped AgSnO/sub 2/ under inductive loads. This well known transfer is due to the anodic arc, which occurs during bounces when the gap between the contacts is shorter than /spl sim/5 /spl mu/m, at the beginning and the end of the bounce. We have demonstrated that welding occurs in the beginning of the bounce, i.e. when the contacts begin to separate under arc, and not when the contacts close under arc at the end of the bounce. It was found that welding occurs mainly with Ag, AgCdO, AgZnO, AgFeRe and AgFeOx contact materials, and under high inrush current produced by lamp loads.","PeriodicalId":299141,"journal":{"name":"Electrical Contacts - 1999.
