This paper presents an innovative method for fault location in distribution networks based on classical circuit analyses. Two synchronized and few nonsynchronized pre- and during-fault voltages are required at few buses ...

This new and general method here called overflow current switching allows a fast, continuous, and smooth transition between scales in wide-range current measurement systems, like electrometers. This is achieved, using a ...

A digital H controller for a two-terminal cryogenic current comparator is designed. To this end, a set of mathematical models covering the actual system is proposed. Simulation results compare the open-and closed-loop ...

Several high temperature superconductor (HTS) tapes have been developed since the late eighties. Due to the new techniques applied for their production, HTS tapes are becoming feasible and practical for many applications. ...

A high-precision power-factor meter, based on zero crossing detectors, is proposed. The influence of the distortion in the input signals is analyzed and low pass filters proposed to prevent this error source. This system ...

This paper presents the assessment of three spectroscopic techniques, i.e., Raman spectroscopy (RS), ultraviolet fluorescence (UVF) spectroscopy, and energy-dispersive X-ray diffraction (ED-XRD), for measuring calcite ...

We study two actions of a stochastic flow psi(t) on the space of 0-currents T of a differentiable manifold M. In particular, we give conditions on a current T to be invariant under these actions. Also, we apply our results ...
