Clarke's alpha, beta and zero components: A possible approach for the conceptual design of instrumentation compatible with IEEE Std. 1459-2000
The paper explains the conceptual design of instrumentation that measures electric quantities defined in the trial-use Std. 1459-2000. It is shown how the Instantaneous-Space-Phasor (ISP) approach, based on α, β, 0 components, ...
Comparative analysis for reactive energy measurement methodologies, under non-sinusoidal conditions in three-phase four-wire circuits
This paper presents some methodologies for reactive energy measurement, considering three modern power theories that are suitable for three-phase four-wire non-sinusoidal and unbalanced circuits. The theories were applied ...
Making Use of Virtual Instrumentation for the Evaluation of Std-1459 and FBD Method in Three-phase Four-Wire Circuits
This paper discusses the design of a virtual instrument for the analysis of three-phase four-wire circuits. Although the flexibility of the proposed instrument in terms of using different methodologies, this paper focuses ...
Virtual instrumentation applied to the implementation of IEEE STD 1459-2000 power definitions
This paper discusses the utilization of Virtual Instrumentation to the implementation and evaluation of different power definitions, so that classical formulations and new definitions can be compared without the necessity ...
An overview of particulate matter measurement instruments
This review article presents an overview of instruments available on the market for measurement of particulate matter. The main instruments and methods of measuring concentration (gravimetric, optical, and microbalance) ...
Impedance e-tongue instrument for rapid liquid assessment
(American Institute of Physics (AIP), 2009-02-01)
We present a compact and easy to handle instrument developed to perform rapid analysis of liquids utilizing an electronic tongue system. Briefly, the e-tongue used here is based on impedance measurements of an array of ...
