Transflective holographic film for head worn display

Jürgen Brugger, Christophe Moser, Eric Tremblay, Victor Javier Cadarso Busto, Jonas Grossenbacher

A display panel assembly comprises a transflective holographic screen, i.e., a transparent screen that reflects light from a projection system, comprising at least a volume hologram, a first protective element and a second protective element, each arranged ...

An Adaptive PMU-Based Wide Area Backup Protection Scheme for Power Transmission Lines

Mohsen Kalantar Neyestanaki

This paper proposes a novel adaptive wide area backup protection scheme for transmission lines. In the proposed scheme, both the faulted line and fault location are determined by a limited number of synchronized phasor measurements. Based on phasor measure ...

Kron reduction methods for plug-and-play control of AC islanded microgrids with arbitrary topology

Giancarlo Ferrari Trecate

In this paper, we provide an extension of the scalable algorithm proposed in (Riverso et al., 2015) for the design of Plug-and-Play (PnP) controllers for AC Islanded microGrids (ImGs). The method in (Riverso et al., 2015) assumes DGUs are arranged in a loa ...

Energy and Latency Optimization in NEM Relay-Based Digital Circuits

Mihai Adrian Ionescu, Antonios Bazigos, Daniel Grogg

Digital circuits based on nanoelectromechanical (NEM) relays hold out the potential of providing an energy efficiency unachievable by conventional CMOS technology. This paper presents a detailed analysis of the operating characteristics of fabricated curve ...

Construction and test of a non-insulated insert coil using coated conductor tape

Pierluigi Bruzzone, Davide Uglietti, Rainer Wesche

A small coated conductor coil (central field 1 T at 200 A) was constructed and tested in order to evaluate the benefit and the possible disadvantages of non insulated, double pancake construction, in particular regarding quench protection. The insert coil ...

An Efficient Method Based on the Electromagnetic Time Reversal to Locate Faults in Power Networks

Mario Paolone, Carlos Alberto Romero Romero, Reza Razzaghi, Gaspard Lugrin

This paper presents a new method based on the electromagnetic time-reversal (EMTR) theory for locating faults in power networks. The applicability of the EMTR technique to locate faults is first discussed. Using the classical transmission-line equations in ...

Modelling of 2G HTS Coated Conductors for Fault Current Limiter Applications

Daniele Colangelo

Thanks to recent scientific achievements, second generation high-temperature superconductor coated conductors (HTS-CCs) can carry enormous current densities with reduced losses. In addition, they are able to switch from a negligible resistivity state to a ...

Effects of nearby buildings on lightning induced voltages on overhead power distribution lines

Mario Paolone, Carlo Alberto Nucci

For the case of urban overhead lines, the presence of nearby buildings is expected to affect the overvoltages induced by nearby cloud-to-ground lightning return strokes. So far, this effect has been seldom taken into account in the literature on the subjec ...

Development of magnet technologies for HTS insert coils

Pierluigi Bruzzone, Davide Uglietti, Boris Stepanov, Rainer Wesche, Stephen Alfred March, Natalia Hanna Glowa

An existing Nb3Sn laboratory magnet generating a magnetic field of 12 T is intended to be upgraded to 16 T by means of the use of a high temperature superconductor (HTS) insert coil. An outline design of the HTS insert coil is presented. In the design, the ...
