Investigating effects of neutral wire and grounding in distribution systems with faults
In some applications like fault analysis, fault location, power quality studies, safety analysis, loss analysis, etc., knowing the neutral wire and ground currents and voltages could be of particular interest. In order to ...
Critical evaluation of FBD, pq and CPT current decompositions for four-wire circuits
This paper investigates the major similarities and discrepancies of three important current decompositions proposed for the interpretation of unbalanced and/or non linear three-phase four-wire circuits. The considered ...
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 ...
Power flow in four-wire distribution networks - General approach
(Institute of Electrical and Electronics Engineers (IEEE), 2003-11-01)
The neutral wire in most power flow software is usually merged into phase wires using Kron's reduction. Since the neutral wire and the ground are not explicitly represented, neutral wire and ground currents and voltages ...
Aeroelastic Analysis of a Typical Section Using of Shape memory wire actuator
Shape memory alloys (SMAs) provide a compact and effective actuation for a variety of mechanical systems. In this paper, a numerical simulation study of a three degree of-freedom airfoil, subjected to two-dimensional ...
Deflection And Flexural Strength Effects On The Roughness Of Aesthetic-coated Orthodontic Wires
(Fundação Odontológica de Ribeirão Preto, 2017)
Three-phase four-wire circuits interpretation by means of different power theories
In order to contribute to the discussion of defining a generalized power theory, valid for unbalanced and non linear circuits, this paper discusses the relationship and discrepancies among four modern power theories. ...
