This article solves the problem of accurate detection of internal faults and classification of
transients in a five-bus interconnected system for phase angle regulators (PARs) and power …

Power transformers are important equipment in power systems and require a responsive
and accurate protection system to ensure system reliability. In this paper, a fault location …

This article discriminates the internal faults from magnetizing inrush for a 3-phase
transformer using a Decision Tree (DT). Afterwards, the internal faults are classified with DT …

Faults during symmetrical power swings cause maloperation of distance relay. Undesired
operation also occurs during unstable power swings causing uncontrolled islanding. Faster …

Several conventional and non-conventional transient conditions cause differential relays
associated with Phase Angle Regulators to malfunction. For Two-core Symmetric Phase …

This paper proposes methods to identify 40 different types of internal faults in an Indirect
Symmetrical Phase Shift Transformer (ISPST). The ISPST was modeled using Power System …

This paper investigates the applicability of time and time-frequency features based
classifiers to distinguish internal faults and other transients-magnetizing inrush, sympathetic …

Transformer is the most essential and costly equipment of the power system. Its protection
against internal fault is achieved by implementing differential protection scheme. In the …

The core task of the differential relay is to protect the power transformer under faulty
condition and to exercise the restrain function in other operating conditions. This paper …

This paper proposes a Decision Tree (DT) based classification of internal faults in a power
transformer. The faults are simulated in Power System Computer Aided Design (PSCAD) …
