Automatic compensation system for impedance measurement [PDF]
, 2002 This paper deals with the realization of the four-pair terminal definition of impedance standards. A simple, though reliable, system is described that allows an automatic compensation of the voltage at the low potential port of impedance standards to be ...

A Novel Stator Turn Fault Detection Technique by Using Equivalent High Frequency Impedance
IEEE Access, 2020 Stator turn fault is the most serious failure in the electrical machine drive which requires immediate detection techniques. Under such a turn fault, the fundamental change is that the high frequency (HF) impedance of the fault phase is significantly ...

Skew Incidence on Concave Wedge With Anisotropic Surface Impedance [PDF]
, 2012 The diffraction of a plane wave at skew incidence by an arbitrary-angled concave wedge with anisotropic impedance faces is studied. Concave wedges are of interest in wireless propagation models, in particular on modeling buildings and reflectors.

Impedance scaling and impedance control [PDF]
Proceedings of the 1997 Particle Accelerator Conference (Cat. No.97CH36167), 2002 When a machine becomes really large, such as the Very Large Hadron Collider (VLHC), of which the circumference could reach the order of megameters, beam instability could be an essential bottleneck. This paper studies the scaling of the instability threshold vs. machine size when the coupling impedance scales in a "normal" way.
