General Fault Admittance Method Solution for a Line-to-Line-to-Line-to-Ground Unsymmetrical Fault

Distance Relaying Algorithm for a Single Line-to- Ground Fault on Single Infeed Transmission Lines

Modern power systems involve large amount of investment. An electric power system comprises of generation, transmission and distribution of electric energy. Growth of power systems has lead to very complex networks extended across large areas. In such situations, the proper functioning of a modern power system is heavily dependent upon the healthy operation of the transmission lines within it. ...

Line graphs associated to the maximal graph

Let $R$ be a commutative ring with identity. Let $G(R)$ denote the maximal graph associated to $R$, i.e., $G(R)$ is a graph with vertices as the elements of $R$, where two distinct vertices $a$ and $b$ are adjacent if and only if there is a maximal ideal of $R$ containing both. Let $Gamma(R)$ denote the restriction of $G(R)$ to non-unit elements of $R$. In this paper we study the various graphi...

Line-Line Fault Detection in Solar Photovoltaic Arrays

ABSTRACT: The 21 century is witnessing a rapid growth in the electrical energy demand due to rise in a large number of electrical gadgets. The conventional sources of energy, which are reliably supplying the energy, are rapidly depleting and the crisis is not near. Therefore, the lookout of non-conventional sources of energy is still on, particularly, the one which can perfectly replace these c...
