This work proposes a method to estimate the electrical constriction resistance of two mating metallic rough surfaces based on the finite element method (FEM). The FEM-based method generates a random array of three-dimensional ...

This work analyzes the effects of the parasitic or stray distributed capacitance to ground in high-voltage environments and assesses the effectiveness of different corrective actions to minimize such effects. To this ...

The electrical resistance, and in particular, the electrical contact resistance (ECR), plays a critical role in the electrical and thermal behaviors of substation connectors. Despite its impact, there are very few research ...

The advent of HTLS (High Temperature, Low Sag) conductors imposes more severe operating conditions on devices such as substation connectors intended for transmission and distribution systems, which are subjected to higher ...

Electronic devices combining sensors, wireless communications, and data processing capability allow easing predictive maintenance tasks in many applications. This paper applies this approach in power connectors for ...

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 ...

One of the main problems that arises when performing short-circuit tests to large loops involving substation connectors is the inductive component of the loop impedance. Transformers used to perform short-circuit tests ...

The contact resistance is the key variable that characterizes the stable performance and long-term service of an electrical connection. It is worth noting that the contact resistance in substation connectors can be several ...

Power devices intended for high-voltage systems must be tested according to international standards, which includes the short-time withstand current test and peak withstand current test. However, these tests require very ...
