“…First of all, a transient structural analysis applied to simulate the insert process and prepare for the next coupled thermo-electrical analysis. In the transient structural analysis, six node contact elements (Contact 174 and target 170) were used on the contact zone and structural 3 dimensional elements (Solid 187) with 10 nodes were used in the other part of the model [8]. The contact area was refined to get a better simulation results.…”

The reliability of electric connection and a stable contact resistance value is usually the most important thing for electrical connector, especially for the electrical connector used in severe environment such as frequently vibration. The present study has investigated the relationship between shrink range and contact resistance of a kind of electrical connector by using the ANSYS software. A indirect coupled structural thermal electrical method was developed to obtain the relations. This paper gives the maximum stress and contact resistance information of connectors in different shrink range value. The contact temperature also was analyzed in this paper.

“…Many studies analyze the effects of one property on another, for example by combining high-temperature cycles and high-power transfer [52], [53], or by modeling thermal effects due to electrical loads [54], [55], or with thermo-mechanical studies [56]. Some other articles study the influence of electrical and thermal properties on a connector's lifetime and aging capacities [57], [58].…”

Abstract-The history of underwater electrical connectors is relatively new: In 1858, the first transatlantic communication cable was created. Since then, the need for subsea electrical connectors has been growing very fast in the offshore industry. Today numerous companies offer a large choice of underwater connectors and assemblies, and it can be intricate to distinguish the different technologies employed for each of them. However the use, deployment, maintenance, and lifetime of any subsea equipment, from a simple sonar to a wave energy converter, relies on its connectors. Hence the design of an underwater electrical connector is to be carefully looked at, and especially for tailor-made applications that have more specific requirements. To produce a good connector, it is necessary to account for thermal, electrical, and mechanical properties, as well as to determine the best materials that should be used for the application. Finally, connector issues go hand in hand with the deployment and operation of any electrical equipment, and it is of interest to review the different techniques for cable connection, as well as the challenges related to cable layout. Those challenges can be of different nature, but they should all be taken into account for any subsea connection.

“…Utilities and system operators must ensure a safe, reliable and continuous delivery of power to customers, while trying to minimize any outage in the service [2]. Power connectors are electromechanical devices [3] intended to provide stable and reliable connection and to transmit electrical power between different conductors or bus bars [4], while minimizing the voltage drop and the associated power losses. They are usually made of copper or aluminum, the latter material being more commonly used in substation connectors.…”

With the increasing use of sensors and wireless communication systems, predictive maintenance is acquiring more and more importance to assess the condition of in-service equipment. Predictive maintenance presents promising cost savings, as it allows minimizing unscheduled power systems faults, which can have very costly and catastrophic consequences. Early stage detection of power system failure requires acquiring, monitoring, and periodically analyzing the condition of the elements involved, such as high-voltage power connectors, since they are critical devices which are often located in key points of power systems. This paper proposes a low-cost online system to determine the contact resistance of high-voltage direct current (DC) and alternating current (AC) power connectors, to determine their health condition in order to apply a predictive maintenance plan. The contact resistance is considered as a reliable indicator of connector's health condition. However, it cannot be directly measured, and the applied strategy differs between DC and AC power systems. Experimental results show a maximum error of 5%, thus proving the accuracy and feasibility of the approach presented in this paper, since the proposed limit of acceptable resistance increase is 20%. This approach can also be applied to many other power systems' elements.
