Inception of Jump resonance in Single phase transformer
2021 4th Biennial International Conference on Nascent Technologies in Engineering (ICNTE), 2021The saturation of the transformer leads to abnormality as the device enters the nonlinear mode of operation. One such condition is ferroresonance in the transformer which has resulted in (2 - 4) pu overvoltage and overcurrent. The saturated transformer can initiate any one of the four modes of ferroresonance depending on initial conditions and circuit ...

Harmonic analysis of ferroresonance in single-phase transformers
2012 IEEE 15th International Conference on Harmonics and Quality of Power, 2012Ferroresonance is a power quality problem that is characterized by distorted overvoltage and current waveforms. This paper reviews the ferroresonance problem associated with a circuit involving an unloaded transformer that is connected to a source through a capacitor, and solution methodologies. A common simplified method based on fundamental frequency

Feedback techniques applied to the single-phase transformer
Transactions of the American Institute of Electrical Engineers, Part II: Applications and Industry, 1957THE ANALYSIS of electric machines makes use of the vector diagram and the equivalent circuit diagram. Both of these methods give the various quantities sought (current, voltage, torque, etc.) under conditions of steady-state operation. When electric machines are used as elements in a general control system, one should rather apply the same techniques ...

Single-Phase Power Transformer Formed Cores
Transactions of the American Institute of Electrical Engineers, 1950For many years power and distribution transformer cores were built of hot-rolled laminations assembled into a core structure. When cold-rolled, oriented strip steel was introduced into transformers, new types of distribution transformer cores were developed.

A Harmonic Model for the Nonlinearities of Single-Phase Transformer with Describing Functions
IEEE Power Engineering Review, 2002In a transformer, the harmonic model is essential for the filter design and analysis of harmonic power flow. Among all of the harmonic analyses of nonlinear devices, the core nonlinearity caused by the transformer hysteresis has received the most interest. Although many harmonic models have been proposed to interpret the nonlinearity of the transformer

A modular solid state transformer with a single-phase medium-frequency transformer
2013 IEEE Electrical Power & Energy Conference, 2013A number of topologies have been introduced for Solid State Transformer (SST); each has its own pros and cons. The three-stage topology, employing a multilevel converter as the first stage, is the most commonly adopted topology in the recent literature. In this paper, a three-stage SST topology is proposed which employs modular multilevel converters in

2019 5th International Conference on Advances in Electrical Engineering (ICAEE), 2019
There is an increasing interest within the industrial community to apply single-phase cycloconverters in variable speed drives and variable frequency applications. For variable speed drive application of cycloconverter to improve the power quality i.e., the harmonic components of the converter’s output voltage should be low which are always measured in

On the Effects of Subsynchronous Interharmonic Voltages on Power Transformers: Single Phase Units
IEEE Transactions on Power Delivery, 2008The effects of subsynchronous interharmonic voltages (SIVs) on three phase power transformers are presented and discussed. In a companion paper, the results of an experiment study a single phase transformer highlighted the need for accurate modeling of the magnetization curve.
