Investigating effects of neutral wire and grounding in distribution systems with faults
(2004-12-01)
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
(2009-12-01)
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
(2011-12-28)
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 distribution networks with earth return
(Elsevier B.V., 2004-06-01)
The problems of wave propagation and power flow in the distribution network composed of an overhead wire parallel to the surface of the ground have not been satisfactorily solved. While a complete solution of the actual ...
Eigenvalue analyses for non-transposed three-phase transmission line considering non-implicit ground wires
(2012-12-11)
This paper presents a method for analyzing electromagnetic transients using real transformation matrices in three-phase systems considering the presence of ground wires. So, for the Z and Y matrices that represent the ...
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 ...
