Proper use of phase-controlled switching technology by controlling the making or breaking
of the circuit breaker (CB) at predetermined phase angles of current or voltage can improve …

Energization of the transformer leads to large magnetizing current called inrush current. It
results in reduction in transformer life, reduction in circuit breaker life, and power quality …

This article proposes a new approach for reducing inrush currents in three-phase three-
legged stacked-core power transformers. Although magnitudes of inrush currents may not …

This paper presents a novel method for the minimization of three-phase transformer inrush
current in the case of sustained switching-on operations. First, a simple mathematical model …

High inrush current severely threats the safe operation of the power system and
transformers, which may lead to mal-operation of overcurrent protection device, internal …

Transformer inrush current can be efficiently mitigated by controlled switching. For
energization of three-phase transformers, several strategies have been developed that …

The main goal of this work is the mitigation of inrush current in a three-phase transformer.
This inrush current appears when energizing a no-load or lightly loaded transformer. It can …

This paper proposes a new model for three-phase transformers with three legs with and
without task under DC bias based on electric and magnetic circuit theory. For the calculation …

At the time of transformer energization, a high current will be drawn by the transformer. This
current is called transient inrush current and it may rise to ten times the nominal full load …

Inrush current with high amplitude is generated when the transformer is energized. On the
one hand, it will have a negative impact on the safety of the transformer itself, and even …
