On the Influence of an Elevated Terrain on the Grounding Resistance of a Vertical Rod

Marcos Rubinstein, Antonio Sunjerga

In this paper, we analyze the grounding resistance of a vertical grounding rod located in an elevated terrain. Tall structures such as wind turbines and mobile phone base stations are often installed in remote and hilly locations to gain more power or to f ...

Reduction of a Cone-Shaped Terrain Grounding Resistance by Remote Grounding

Marcos Rubinstein, Antonio Sunjerga, Farhad Rachidi-Haeri

Tall structures such as wind turbines and mobile phone base stations are often installed in remote and hilly locations to gain more power or to have line of sight to end users. Those locations are usually very rocky and characterized by a low-conductivity ...

Design of DEMO PF Coils Based on Cable-in-Conduit Conductor

Pierluigi Bruzzone, Kamil Sedlák, Mithlesh Kumar

The poloidal field (PF) coils are designed based on the requirements defined by the EUROfusion 2015 DEMO baseline. The conductors are forced flow, NbTi cable-in-conduit. The design addresses the dimensioning of the winding pack, the electromagnetic field c ...

Load Flow in Multiphase Distribution Networks: Existence, Uniqueness, Non-Singularity and Linear Models

Jean-Yves Le Boudec, Andrey Bernstein, Cong Wang

This paper considers unbalanced multiphase distribution systems with generic topology and different load models, and extends the Z-bus iterative load-flow algorithm based on a fixed-point interpretation of the AC load-flow equations. Explicit conditions fo ...

Transient Impedance of Interconnected Wind Turbine Grounding Systems

Marcos Rubinstein, Antonio Sunjerga, Farhad Rachidi-Haeri, Qi Li

Wind turbines are very vulnerable to lightning because of their height, sharp edges and remote locations often with low soil conductivity. In this paper we present numerical simulations of the impedance of a typical wind turbine grounding geometry. We anal ...

An experimental field study of the grounding system response of tall wind turbines to impulse surges

Marcos Rubinstein, Antonio Sunjerga, Nicolas Mora Parra

In this work, an experimental investigation of the grounding system behavior of tall wind turbines in both time and frequency domains is presented. Two scenarios were considered: in the first one, measurements were carried out on the grounding system embed ...

Pull-Out Behavior of CFRP Single-Strap Ground Anchors

Thomas Keller, Anastasios Vassilopoulos, Haifeng Fan

Pull-out experiments were performed on four carbon fiber-reinforced polymer (CFRP) ground anchors simulating their applications in rock and soil. The CFRP tendons used in these anchors comprise a single-strap end on both ground and air sides. On the ground ...

Assessing the degradation of compliant electrodes for soft actuators

Herbert Shea, Samuel Rosset, Alexandre Poulin, Christine Anne de Saint-Aubin

We present an automated system to measure the degradation of compliant electrodes used in dielectric elastomer actuators (DEAs) over millions of cycles. Electrodes for DEAs generally experience biaxial linear strains of more than 10%. The decrease in elect ...
