This study presents a new classification of voltage sags which is based on its types,
characteristic voltage and zero‐sequence component of voltage. It is extremely difficult to …

This paper presents a new algorithm, namely, a three-phase-angle algorithm, for accurate
characterization of three-phase unbalanced voltage sags, associated with line-to-line and …

In this paper, a new power quality (PQ) index, namely active voltage component (AVC), has
been developed using the help of symmetrical component analysis (SCA). Furthermore, the …

Distribution static synchronous compensator (D-STATCOM) has been developed and
attained a great interest to compensate the power quality disturbances of distribution …

First, the features of various power quality disruptions (PQDs) and their standard have been
discussed in brief to reveal the most important PQDs. Further, based on huge economic …

The effectiveness of phase over-current protection cannot be evaluated by using time-
current graphs alone. This article develops a method to evaluate and optimize the phase …

This paper presents a new method to characterize and detect the type of voltage sag
through complex voltage unbalance factor (CVUF). Different types of voltage dip due to …

This paper suggests a modification in symmetrical component (SC) method, used for
characterization and classification of voltage sags, by incorporating an angle, ɸ, in it. The ɸ …

This paper highlights the shortfalls, existing in the methods, currently used for the
characterization of voltage sags, from recorded waveforms. Test waveform, available with …

First, using sequence components of the voltages, this paper derives a new voltage sag
index, namely,“S.” Then, with the help of the derived index,“S,” a new classification of …
