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 ...
Evaluation of a multiobjective performance index for distribution systems with distributed generation
(2005-12-14)
Here a multiobjective performance index for distribution systems with distributed generation based on a steady-state analysis of the network is proposed. This index quantifies the distributed generation impact on total ...

Fuzzy risk index for power transformer failures due to external short-circuits
(ELSEVIER SCIENCE SA, 2009)
A novel methodology to assess the risk of power transformer failures caused by external faults, such as short-circuit, taking the paper insulation condition into account, is presented. The risk index is obtained by contrasting ...
